tinycolor2

What is tinycolor2?

The tinycolor2 npm package is a small, fast library for color manipulation and conversion in JavaScript. It allows for reading, editing, and converting colors between various color formats, as well as checking color properties and performing adjustments.

What are tinycolor2's main functionalities?

Color Parsing

Parse a string input to create a tinycolor instance. It accepts various color formats like HEX, RGB, HSL, HSV, and names.

var tinycolor = require('tinycolor2');
var color = tinycolor('#f0e');

Color Manipulation

Manipulate colors by chaining methods like lighten, darken, saturate, desaturate, etc., and then output to a desired format.

var newColor = tinycolor('red').lighten(10).desaturate(5).toHexString();

Color Comparison

Check readability and contrast between two colors to ensure that text is readable on a given background color.

var isReadable = tinycolor.isReadable('#000', '#fff');

Color Validation

Validate a color to check if it is a proper color that can be parsed and manipulated.

var isValid = tinycolor('red').isValid();

Color Conversion

Convert colors to different formats like RGB, HEX, HSL, HSV, etc.

var rgbString = tinycolor('red').toRgbString();

Other packages similar to tinycolor2

chroma-js

Chroma.js is a powerful library for all kinds of color conversions and color scales. It's more feature-rich and has more color scale options compared to tinycolor2.

color

The 'color' package is another color manipulation library that supports color conversion and manipulation. It has a chainable API similar to tinycolor2 but also includes support for color profiles like Apple's Display P3.

color-convert

Color-convert is a library that focuses on converting colors between different models. It has a simpler API for conversions without additional color manipulation features.

Usage

var t = tinycolor("red");

t.toHex() // "ff0000"
t.toHexString() // "#ff0000"
t.toHex8() // "ffff0000"
t.toHex8String() // "#ffff0000"
t.toRgb() // {"r":255,"g":0,"b":0} or {"r":255,"g":0,"b":0,"a":0.5}
t.toRgbString() // "rgb(255, 0, 0)" or "rgba(255, 0, 0, 0.5)"
t.toPercentageRgb() // {"r":100,"g":0,"b":0} or {"r":100,"g":0,"b":0,"a":0.5}
t.toPercentageRgbString() // "rgb(100%, 0%, 0%)" or "rgba(100%, 0%, 0%, 0.5)"
t.toHsv() // {"h":0,"s":1,"v":1}
t.toHsvString() // "hsv(0, 100%, 100%)"
t.toHsl() // {"h":0,"s":1,"l":0.5}
t.toHslString() // "hsl(0, 100%, 50%)"
t.toName() // "red"

tinycolor may also be included as a node module like so:

npm install tinycolor2

Then it can be used:

var tinycolor = require("./tinycolor");

Accepted String Input

The string parsing is very permissive. It is meant to make typing a color as input as easy as possible. All commas, percentages, parenthesis are optional, and most input allow either 0-1, 0%-100%, or 0-n (where n is either 100, 255, or 360 depending on the value).

HSL and HSV both require either 0%-100% or 0-1. RGB requires either 0-255 or 0%-100%. If you call tinycolor.fromRatio, any input can also accept 0-1 Here are some examples of string input:

red
#fff
fff
#ffffff
ffffff
#ffffffff
ffffffff
rgb(255, 0, 0)
rgb 255 0 0
hsl(0, 100, 50)
hsl(0, 100%, 50%)
hsl 0 100 50
hsl 0 100% 50%
hsv(0, 100%, 100%)
hsv(0, 100, 100)
hsv 0 100% 100%
hsv 0 100 100

Accepted Object Input

If you are calling this from code, you may want to use object input. Here are examples of the different types of accepted object inputs:

{ r: 255, g: 0, b: 0 }
{ r: 255, g: 0, b: 0, a: .5 }
{ r: 1, g: 0, b: 0 }
{ h: 0, s: 100, l: 50 }
{ h: 0, s: 100, v: 100 }
// etc...

Color Utilities

tinycolor.equals(color1, color2)

Color Modification

Modification functions may take an amount variable from 0 - 100, indicating how much the effect should be applied.

tinycolor.lighten(color, amount = 10)
tinycolor.darken(color, amount = 10)
tinycolor.desaturate(color, amount = 10)
tinycolor.saturate(color, amount = 10)
tinycolor.greyscale(color)

Color Combinations

Combination functions return an Array of TinyColor objects.

tinycolor.analogous(color, results = 6, slices = 30)
tinycolor.complement(color)
tinycolor.monochromatic(color, results = 6)
tinycolor.splitcomplements(color)
tinycolor.triad(color)
tinycolor.tetrad(color)

Readability

Analyze 2 colors and returns an object with the following properties. brightness is difference in brightness between the two colors. color: difference in color/hue between the two colors.

tinycolor.readability(color1, color2);

Ensure that foreground and background color combinations provide sufficient contrast.

tinycolor.readable(color1, color2);

Given a base color and a list of possible foreground or background colors for that base, returns the most readable color.

tinycolor.mostReadable(baseColor, colorList);

See index.html in the project for a demo.
