Programmatic JavaScript/TypeScript SDK for generating mathematically accurate, accessible color palettes. Same engine as the Rampa CLI, designed for use in applications, build tools, and design systems.

Installation

npm install @basiclines/rampa-sdk

Vanilla JS (CDN / Script Tag)

A pre-built browser bundle is available on every GitHub Release. No bundler or build step needed — just drop a <script> tag:

<script src="https://github.com/basiclines/rampa-studio/releases/latest/download/rampa-sdk.min.js"></script>
<script>
  // Everything is available under the global `Rampa` object
  const palette = Rampa.rampa('#3b82f6').size(5);
  console.log('' + palette(1));   // first color
  console.log(palette.palette);   // all colors

  const css = Rampa.rampa('#3b82f6').output('css');
  const mixed = Rampa.rampa.mix('#ff0000', '#0000ff', 0.5);

  const linear = new Rampa.LinearColorSpace('#ffffff', '#000000').size(10);
  console.log('' + linear(5)); // midpoint gray

  const c = Rampa.color('#3b82f6');
  console.log(c.hex, c.rgb, c.luminance);
</script>

Pin a specific version by replacing latest with the tag name:

Quick Start

import { rampa } from '@basiclines/rampa-sdk';

// Generate a 10-color palette from blue
const palette = rampa('#3b82f6');
palette(1)            // first color (ColorAccessor)
palette(5).oklch()    // format conversion

// Custom size with lightness range
const custom = rampa('#3b82f6').size(5).lightness(10, 90);
custom(3)             // third color

// Add complementary harmony
const harmonies = rampa('#3b82f6').add('complementary');
harmonies.ramps       // [base, complementary]

// Output as CSS variables
const css = rampa('#3b82f6').output('css');

API

`rampa(baseColor)`

Creates a callable color palette. Accepts any valid CSS color (hex, hsl, rgb, oklch, named colors). All methods are chainable in any order, and the result is always callable with a 1-based index.

const palette = rampa('#3b82f6');
const palette = rampa('rgb(59, 130, 246)');
const palette = rampa('hsl(217, 91%, 60%)');
const palette = rampa('oklch(62.3% 0.214 259)');

palette(1)           // first color
palette(5).hsl()     // format conversion
palette.palette      // string[] of all colors

Builder Methods

All builder methods return the same callable for chaining in any order.

`.size(steps)`

Number of colors in the palette (2-100, default: 10).

rampa('#3b82f6').size(5);

`.format(type)`

Color format for output values: hex, hsl, rgb, oklch (default: hex).

rampa('#3b82f6').format('hsl');
// palette(1) → 'hsl(0, 0%, 0%)', palette(2) → 'hsl(212, 69%, 25%)', ...

`.lightness(start, end)`

Lightness range 0-100 (default: 0, 100).

rampa('#3b82f6').lightness(10, 90);

`.saturation(start, end)`

Saturation range 0-100 (default: 100, 0).

rampa('#3b82f6').saturation(80, 20);

`.hue(start, end)`

Hue shift in degrees (default: -10, 10).

rampa('#3b82f6').hue(-30, 30);

`.lightnessDistribution(type)`, `.saturationDistribution(type)`, `.hueDistribution(type)`

Distribution curve for each channel (default: linear).

Available distributions: linear, geometric, fibonacci, golden-ratio, logarithmic, powers-of-2, musical-ratio, cielab-uniform, ease-in, ease-out, ease-in-out

rampa('#3b82f6')
  .lightnessDistribution('fibonacci')
  .saturationDistribution('ease-out')
  .hueDistribution('golden-ratio');

`.tint(color, opacity, blend?)`

Apply a tint color over the palette.

color — Any valid CSS color
opacity — Tint strength 0-100
blend — Blend mode (default: normal)

Available blend modes: normal, multiply, screen, overlay, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, exclusion, hue, saturation, color, luminosity, plus-darker, plus-lighter

rampa('#3b82f6')
  .tint('#FF0000', 15, 'overlay');

`.add(type)` / `.add('shift', degrees)`

Add a harmony ramp. Can be called multiple times.

Available harmony types:

complementary — Opposite on color wheel (+180°)
triadic — 3 colors, 120° apart
analogous — Adjacent colors, 30° apart
split-complementary — 2 colors near opposite
square — 4 colors, 90° apart
compound — Complementary + split
shift — Custom hue rotation by N degrees

rampa('#3b82f6')
  .add('complementary')
  .add('triadic')
  .add('shift', 45);

Accessing Colors

Call the palette with a 1-based index to get a ColorAccessor:

const palette = rampa('#3b82f6').size(5).lightness(10, 90);

palette(1)           // ColorAccessor — first color
palette(3).hsl()     // format conversion
palette(5).oklch()   // any format
`${palette(1)}`      // works in template literals

palette.palette      // string[] of all colors
palette.ramps        // RampResult[] (base + harmonies)

Output Methods

`.output(format, prefix?)`

Export the palette as 'css', 'json', or 'text'. Optional prefix sets variable/ramp names (default: 'base').

// CSS custom properties
rampa('#3b82f6').size(5).output('css', 'primary');
// :root {
//   /* primary */
//   --primary-0: #000000;
//   --primary-1: #143d6b;
//   --primary-2: #4572ba;
//   --primary-3: #b1b9ce;
//   --primary-4: #ffffff;
// }

// JSON
rampa('#3b82f6').size(5).output('json', 'primary');
// {
//   "ramps": [
//     {
//       "name": "primary",
//       "baseColor": "#3b82f6",
//       "colors": ["#000000", "#143d6b", "#4572ba", "#b1b9ce", "#ffffff"]
//     }
//   ]
// }

// Plain text (one color per line)
rampa('#3b82f6').size(5).output('text');
// #000000
// #143d6b
// #4572ba
// #b1b9ce
// #ffffff

`.ramps` / `.palette`

Access the generated ramps and colors directly as properties:

const result = rampa('#3b82f6').size(5).add('complementary');
result.palette                // base ramp colors: ['#000000', '#143d6b', ...]
result.ramps                  // all ramps: [{ name: 'base', ... }, { name: 'complementary', ... }]
result.ramps[1].colors        // complementary ramp colors

`color(input)`

Inspect, transform, mix, and export a single color. Equivalent to rampa color in the CLI.

All property values use 0-1 normalized ranges to match CSS spec conventions:

Property	Range
`hsl.h`	0–360 (degrees)
`hsl.s`, `hsl.l`	0–1
`oklch.l`	0–1
`oklch.c`	0–0.4 (native OKLCH scale)
`oklch.h`	0–360 (degrees)

import { color } from '@basiclines/rampa-sdk';

const c = color('#fe0000');
c.hex              // '#fe0000'
c.rgb              // { r: 254, g: 0, b: 0 }
c.hsl              // { h: 0, s: 1.0, l: 0.5 }
c.oklch            // { l: 0.628, c: 0.258, h: 29 }
c.luminance        // 0.628

// Format conversion (string output uses CSS conventions: percentages)
c.format('hsl')    // 'hsl(0, 100%, 50%)'
c.format('rgb')    // 'rgb(254, 0, 0)'
c.format('oklch')  // 'oklch(62.8% 0.258 29)'

// Export
c.output('json')           // JSON with all formats
c.output('css', 'brand')   // CSS custom properties with prefix
c.output('text')           // plain hex string

// String coercion
`${c}`             // '#fe0000'

Color Transforms

All transforms operate in OKLCH space and return a new immutable Color. Chain freely.

// Absolute deltas — clamped to valid range
c.lighten(0.1)           // L += 0.1 (OKLCH lightness, 0-1)
c.darken(0.1)            // L -= 0.1
c.saturate(0.05)         // C += 0.05 (OKLCH chroma)
c.desaturate(0.05)       // C -= 0.05
c.rotate(30)             // H += 30° (hue rotation)

// All accept negative values: lighten(-0.1) === darken(0.1)

// Set absolute OKLCH values
c.set({ lightness: 0.48 })             // set L
c.set({ chroma: 0.15, hue: 200 })     // batch set

// Chain transforms
color('#66b172').lighten(0.1).desaturate(0.05).hex
// → bright desaturated green, no throwaway converters

Mix (color space interpolation)

Like CSS color-mix() — interpolates between two colors in a chosen color space.

c.mix('#0000ff', 0.5)            // 50% mix in oklch (default)
c.mix('#0000ff', 0.18, 'lab')    // explicit color space
c.mix('#0000ff', 0.18, 'srgb')   // sRGB interpolation

Blend (compositing modes)

Like Photoshop/CSS blend modes — composites two colors with an opacity and a blend mode.

c.blend('#0000ff', 0.15, 'multiply')
c.blend('#0000ff', 0.15, 'screen')
c.blend('#0000ff', 0.15, 'overlay')

`rampa.convert(color, format)`

Standalone utility to convert a color to a different format.

rampa.convert('#fe0000', 'hsl');    // 'hsl(0, 100%, 50%)'
rampa.convert('#fe0000', 'rgb');    // 'rgb(254, 0, 0)'
rampa.convert('#fe0000', 'oklch');  // 'oklch(62.8% 0.257 29)'
rampa.convert('#fe0000', 'hex');    // '#fe0000'

`rampa.mix(color1, color2, t)`

Mix two colors in OKLCH space at a given ratio. Produces perceptually uniform transitions — hues travel the color wheel naturally, lightness steps look even, and chroma stays vivid instead of dipping through gray.

rampa.mix('#ff0000', '#0000ff', 0);    // '#ff0302' (start color)
rampa.mix('#ff0000', '#0000ff', 0.5);  // midpoint — vivid purple, not muddy gray
rampa.mix('#ff0000', '#0000ff', 1);    // '#0031e5' (end color)
rampa.mix('#000000', '#ffffff', 0.5);  // perceptual mid-gray

Generate a gradient with multiple steps:

const steps = 10;
const gradient = Array.from({ length: steps }, (_, i) =>
  rampa.mix('#ff0000', '#0000ff', i / (steps - 1))
);

`lint(foreground, background)`

Evaluate contrast between two colors. Returns score, pass/fail levels, and lint warnings. Default mode is 'apca'.

import { lint } from '@basiclines/rampa-sdk';

// APCA (default) — returns Lc value
const result = lint('#ffffff', '#1e1e2e');
result.score      // -104.3 (Lc value)
result.pass       // true (at least one level passes)
result.levels     // [{ name: 'Preferred body text', threshold: 90, pass: true }, ...]
result.warnings   // []

// WCAG 2.x — chain .mode('wcag')
const wcag = lint('#777', '#ffffff').mode('wcag');
wcag.score        // 4.48 (contrast ratio)
wcag.levels       // [{ name: 'AAA Normal text', threshold: 7, pass: false }, ...]

// Export
result.output('json')  // JSON with full result
result.output('text')  // readable text report
result.output('css')   // CSS custom properties

Lint warnings fire automatically:

Near-identical colors (deltaE < 3)
Contrast below minimum usable threshold
Pure #000000 or #ffffff detected

Examples

Design System Palette

import { rampa } from '@basiclines/rampa-sdk';

const primary = rampa('#3b82f6')
  .size(10)
  .lightness(5, 95)
  .saturationDistribution('ease-out');

const neutral = rampa('#64748b')
  .size(10)
  .saturation(20, 0);

const danger = rampa('#ef4444')
  .size(10)
  .lightness(10, 90);

// Access individual colors
primary(5)         // mid-tone blue
neutral(1)         // darkest gray
danger(8).hsl()    // light red in HSL

Full Palette with Harmonies

const palette = rampa('#3b82f6')
  .size(10)
  .lightness(5, 95)
  .lightnessDistribution('ease-in-out')
  .add('complementary')
  .add('analogous');

palette(1)          // first base color
palette.ramps[1]    // complementary ramp
palette.ramps[2]    // analogous ramp

CSS Variables for a Theme

const theme = rampa('#3b82f6')
  .size(10)
  .add('complementary')
  .tint('#FFD700', 5, 'overlay')
  .output('css');

// Inject into page
const style = document.createElement('style');
style.textContent = theme;
document.head.appendChild(style);

Build Tool Integration

import { rampa } from '@basiclines/rampa-sdk';
import { writeFileSync } from 'fs';

const colors = rampa('#3b82f6')
  .size(10)
  .format('hsl');

// Write to a tokens file
writeFileSync('tokens.json', JSON.stringify({ colors: colors.palette }, null, 2));

CLI Parity

The SDK produces identical output to the CLI. These are equivalent:

# CLI
rampa --color "#3b82f6" --size=5 --lightness 10:90 --add=complementary --output json

// SDK
rampa('#3b82f6').size(5).lightness(10, 90).add('complementary').output('json');

Color Spaces

Color spaces let you create structured palettes from a set of anchor colors and query them semantically. Three geometric primitives are available:

LinearColorSpace — 1D interpolated ramp
PlaneColorSpace — 2D saturation×lightness plane
CubeColorSpace — 3D trilinear interpolation cube

`LinearColorSpace`

Interpolates between two colors to produce an evenly-spaced ramp.

import { LinearColorSpace } from '@basiclines/rampa-sdk';

const neutral = new LinearColorSpace('#ffffff', '#000000').size(24);
neutral(1)               // → '#ffffff' (lightest, returns string directly)
neutral(12)              // → '#666666' (mid gray)
neutral(12).hsl()        // → 'hsl(0, 0%, 40%)'
neutral.palette          // → string[24]

Ramp introspection

Access individual steps as full Color objects with .at(), or get all steps with .colors():

const ramp = new LinearColorSpace('#000', '#fff').size(12);

ramp.at(3)                       // → Color (0-based index)
ramp.at(3).oklch.c               // → chroma at step 3
ramp.at(3).lighten(0.1).hex      // → transform a ramp step

ramp.colors()                    // → Color[]
ramp.colors().map(c => c.oklch.c)  // → chroma curve across ramp

.at() is 0-based (like Array.at()), while the callable ramp(n) remains 1-based for backward compatibility.

Lookup table mode

Set .interpolation(false) for a plain lookup table — no interpolation, just indexed access to the exact colors you provide:

const base = new LinearColorSpace(
  '#45475a', '#f38ba8', '#a6e3a1', '#f9e2af',
  '#89b4fa', '#f5c2e7', '#94e2d5', '#a6adc8'
).interpolation(false).size(8);

base(1)  // → '#45475a' (exact, no interpolation)
base(3)  // → '#a6e3a1'

`PlaneColorSpace`

Creates a 2D color plane for a single hue, anchored to shared dark/light values. Create one plane per hue.

Y(lightness)
1 │  light ─────────── hue
  │    │                 │
  │    │   interpolated  │
  │    │                 │
0 │  dark ─────────── dark
  └──────────────────────── X(saturation)
      0                  1

At Y=0 the entire row converges to the dark anchor.

import { PlaneColorSpace } from '@basiclines/rampa-sdk';

// One plane per hue, reuse dark/light anchors
const red  = new PlaneColorSpace('#1e1e2e', '#cdd6f4', '#f38ba8').size(6);
const blue = new PlaneColorSpace('#1e1e2e', '#cdd6f4', '#89b4fa').size(6);

red(3, 5)          // → ColorAccessor (saturation=3, lightness=5)
red(0, 3)          // → achromatic at lightness 3 (no hue influence)
red(5, 5)          // → full hue color
red(0, 0)          // → dark anchor
red.palette        // → string[36] (6²)

// Ramp introspection
red.at(3, 5)              // → Color at (saturation=3, lightness=5)
red.at(3, 5).oklch.c      // → chroma at that coordinate
red.colors()              // → Color[] (flat, row-major)

// Template literals and concatenation work directly
`background: ${red(3, 5)};`  // → 'background: #ab34cd;'

// Format conversion
red(3, 5).hsl()    // → 'hsl(280, 60%, 50%)'
red(3, 5).oklch()  // → 'oklch(52.3% 0.198 310)'

`CubeColorSpace`

Creates a 3D color cube from 8 corner colors via trilinear interpolation. The constructor keys become alias names for semantic lookups.

import { CubeColorSpace } from '@basiclines/rampa-sdk';

const { r, b, tint } = new CubeColorSpace({
  k: '#1e1e2e',    // origin (0,0,0)
  r: '#f38ba8',    // x axis
  g: '#a6e3a1',    // y axis
  b: '#89b4fa',    // z axis
  y: '#f9e2af',    // x+y
  m: '#cba6f7',    // x+z
  c: '#94e2d5',    // y+z
  w: '#cdd6f4',    // x+y+z
}).size(6);

r(4)                     // → strong red
tint({ r: 4, b: 2 })     // → red-blue blend
tint({ w: 3 })           // → mid-white (all axes at 3)

// Ramp introspection
cube.at(2, 3, 1)         // → Color at (x=2, y=3, z=1)
cube.colors()            // → Color[]

Custom vocabulary

The alias names are whatever you put in the constructor — not limited to ANSI names:

const space = new CubeColorSpace({
  dark:    '#1a1a2e',
  warm:    '#e74c3c',
  nature:  '#2ecc71',
  ocean:   '#3498db',
  sunset:  '#f39c12',
  berry:   '#9b59b6',
  mint:    '#1abc9c',
  light:   '#ecf0f1',
}).size(6);

space({ warm: 4, ocean: 2 })  // → warm-ocean blend

How aliases map to the cube

The 8 keys map to cube corners by insertion order:

Position	Key #	Cube coords	Axis mask
1st	origin	(0,0,0)	—
2nd	x	(1,0,0)	x
3rd	y	(0,1,0)	y
4th	z	(0,0,1)	z
5th	xy	(1,1,0)	x+y
6th	xz	(1,0,1)	x+z
7th	yz	(0,1,1)	y+z
8th	xyz	(1,1,1)	x+y+z

When you call tint({ r: 4, b: 2 }), each alias's mask is multiplied by its intensity and merged with Math.max to produce cube coordinates.

Interpolation modes

LinearColorSpace, PlaneColorSpace, and CubeColorSpace all support configurable interpolation:

Mode	Description
`'oklch'` (default)	Perceptually uniform — hues travel the color wheel, even lightness steps
`'lab'`	CIE Lab* — perceptual but no hue rotation
`'rgb'`	Linear RGB — fast but perceptually uneven
`false`	No interpolation — plain lookup table (LinearColorSpace only)

// LinearColorSpace
new LinearColorSpace('#ff0000', '#0000ff').interpolation('oklch').size(10)
new LinearColorSpace('#ff0000', '#0000ff').interpolation('lab').size(10)
new LinearColorSpace('#f00', '#0f0', '#00f').interpolation(false).size(3)

// PlaneColorSpace
new PlaneColorSpace('#000', '#fff', '#f00').interpolation('oklch').size(6)
new PlaneColorSpace('#000', '#fff', '#f00').interpolation('lab').size(6)

// CubeColorSpace
new CubeColorSpace({ ... }).interpolation('lab').size(6)

Distribution curves

All color space classes support .distribution(scale) to apply non-linear step spacing. When not set, steps are evenly spaced (zero overhead on the default path).

Available scales: ease-in, ease-out, ease-in-out, fibonacci, golden-ratio, geometric, logarithmic, powers-of-2, musical-ratio, cielab-uniform

// Ease-in: bunch colors toward the start, spread out toward the end
const ramp = new LinearColorSpace('#ffffff', '#000000')
  .distribution('ease-in')
  .size(10);

// Fibonacci spacing on a 2D plane
const red = new PlaneColorSpace('#1e1e2e', '#cdd6f4', '#f38ba8')
  .distribution('fibonacci')
  .size(8);

// Golden ratio on a cube
const space = new CubeColorSpace({ ... })
  .distribution('golden-ratio')
  .size(6);

Color accessor

All color space lookups return a ColorAccessor — a string that works directly in template literals and concatenation, with conversion methods:

const c = red(3, 5);
`${c}`             // → '#ab34cd' (string coercion)
'bg: ' + c         // → 'bg: #ab34cd' (concatenation)
c.hex()            // → '#ab34cd'
c.hsl()            // → 'hsl(280, 60%, 50%)'
c.rgb()            // → 'rgb(171, 52, 205)'
c.oklch()          // → 'oklch(52.3% 0.198 310)'
c.luminance        // → 0.52 (perceptual, 0–1)

Use .format() on the color space to change the default output format:

const rgbSpace = new PlaneColorSpace('#000', '#fff', '#f00').format('rgb').size(6);
`${rgbSpace(3, 5)}`  // → 'rgb(255, 128, 128)'
rgbSpace(3, 5).hex() // → '#ff8080' (still available)

Image Palette Extraction

Extract color palettes from images with three tiers of analysis: raw unique colors, dominant color clusters, and ANSI-classified palettes.

Requires fast-png and jpeg-js (installed as dependencies). Supports PNG and JPEG files.

`palette(filePath)`

import { palette } from '@basiclines/rampa-sdk';

const p = await palette('photo.jpg');

Dominant Colors

Top N color groups via k-means clustering in OKLCH space:

p.dominant()                     // → PaletteEntry[] (top 10)
p.dominant({ count: 5 })        // top 5
p.dominant({ tolerance: 10 })   // wider clustering (default: 4)

// Shortcut with .at() (0-based, like ramp.at())
p.at(0)                          // most dominant color
p.at(0).color.hex               // → '#2d2a18'
p.at(0).frequency               // → 0.278 (27.8% of pixels)
p.at(0).color.lighten(0.1).hex  // chain transforms

Raw Palette

All unique colors with near-duplicates merged:

p.raw()                          // → PaletteEntry[]
p.raw({ tolerance: 3 })         // deltaE merge threshold (default: 2)
p.raw({ maxColors: 500 })       // cap output (default: 1000)

ANSI Palette

Colors classified into terminal color categories:

p.ansi()
// → { red: PaletteEntry[], green: [...], blue: [...], ... }

p.ansi({ count: 3 })            // max 3 per category (default: 5)

Categories: black, red, green, yellow, blue, magenta, cyan, white

Group by OKLCH Property

Group colors into buckets by lightness, chroma, or hue:

p.group({ by: 'L' })            // → { darkest, dark, mid, light, lightest }
p.group({ by: 'C' })            // → { gray, muted, saturated, vivid }
p.group({ by: 'H' })            // → { red, orange, yellow, green, cyan, blue, purple, pink }

p.group({ by: 'L', count: 3 })  // max 3 colors per bucket
p.group({ by: 'L', tolerance: 10 })  // wider dedup within buckets

Custom bucket boundaries:

p.group({
  by: 'L',
  buckets: [
    { name: 'dark', min: 0, max: 0.3 },
    { name: 'mid',  min: 0.3, max: 0.7 },
    { name: 'light', min: 0.7, max: 1.0 },
  ],
})

Sorting with `.sortBy()`

All array and grouped results support .sortBy() for reordering:

// Sort dominant colors by lightness (dark → light)
p.dominant({ count: 5 }).sortBy('L')

// Sort within each group bucket
p.group({ by: 'C' }).sortBy('L')    // chroma groups, each sorted dark→light
p.ansi().sortBy('L')                 // ANSI categories, each sorted dark→light

// Sort fields: 'L' (lightness), 'C' (chroma), 'H' (hue), 'frequency'
p.raw().sortBy('H')                  // all colors sorted by hue angle

// Chainable — returns a new sorted result
p.dominant().sortBy('L').sortBy('C')

Extras

p.average()                      // → Color (weighted OKLCH average)
p.temperature()                  // → 'warm' | 'cool' | 'neutral'

Output

p.output('json')                 // full analysis as JSON
p.output('css', 'photo')        // CSS custom properties
p.output('text')                 // readable text

PaletteEntry Shape

interface PaletteEntry {
  color: Color;       // full Color with transforms
  frequency: number;  // 0-1, percentage of sampled pixels
}
