Color Scales

Provides a set of color scales for different colors like blue, red, and green. Each color scale has multiple shades that can be used for different UI elements.

import { blue, red, green } from '@radix-ui/colors';

const primaryColor = blue.blue9;
const errorColor = red.red9;
const successColor = green.green9;

console.log(primaryColor); // Outputs: #3b82f6
console.log(errorColor); // Outputs: #ef4444
console.log(successColor); // Outputs: #10b981

Dark Mode Support

Provides dark mode variants for each color scale, allowing for seamless integration with dark mode themes.

import { blueDark, redDark, greenDark } from '@radix-ui/colors';

const primaryColorDark = blueDark.blue9;
const errorColorDark = redDark.red9;
const successColorDark = greenDark.green9;

console.log(primaryColorDark); // Outputs: #1e40af
console.log(errorColorDark); // Outputs: #b91c1c
console.log(successColorDark); // Outputs: #047857

Accessibility

Includes color shades that are optimized for accessibility, ensuring that text and UI elements are readable for users with visual impairments.

import { blue, red, green } from '@radix-ui/colors';

const accessiblePrimary = blue.blue11;
const accessibleError = red.red11;
const accessibleSuccess = green.green11;

console.log(accessiblePrimary); // Outputs: #1e3a8a
console.log(accessibleError); // Outputs: #991b1b
console.log(accessibleSuccess); // Outputs: #065f46

Define your themes

import { createCss } from "@stitches/react";
import {
  slate,
  blue,
  red,
  yellow,
  green,
  slateDark,
  blueDark,
  redDark,
  yellowDark,
  greenDark,
} from "@radix-ui/colors";

const { styled, theme } = createCss({
  theme: {
    colors: {
      ...slate,
      ...blue,
      ...red,
      ...yellow,
      ...green,
    }
  }
});

const darkTheme = theme({
  colors: {
    ...slateDark,
    ...blueDark,
    ...redDark,
    ...yellowDark,
    ...greenDark,
  },
});

Use the colors

Each scale has 11 steps, from 000 to 1000.

const Button = styled("button", {
  backgroundColor: "$blue200",
  color: "$blue900",
  "&:hover": {
    backgroundColor: "$blue300"
  },
  "&:active": {
    backgroundColor: "$blue400"
  }
});

Aliasing

It can be helpful to provide semantic token aliases, so devs don't need to think as much about mapping steps to use cases.

const { styled, theme } = createCss({
  theme: {
    colors: {
      ...slate,
      ...blue,
      ...red,
      ...green,

      // Semantic aliases

      grayBgApp: "$slate000",
      grayBgLight: "$slate100",
      grayBg: "$slate200",
      grayBgHover: "$slate300",
      grayBgActive: "$slate400",
      grayLine: "$slate500",
      grayBorder: "$slate600",
      grayBorderHover: "$slate700",
      grayPure: "$slate800",
      grayText: "$slate900",

      accentBase: "$blue000",
      accentBgLight: "$blue100",
      accentBg: "$blue200",
      accentBgHover: "$blue300",
      accentBgActive: "$blue400",
      accentLine: "$blue500",
      accentBorder: "$blue600",
      accentBorderHover: "$blue700",
      accentPure: "$blue800",
      accentText: "$blue900",
      
      dangerBase: "$red000",
      dangerBgLight: "$red100",
      dangerBg: "$red200",
      dangerBgHover: "$red300",
      dangerBgActive: "$red400",
      dangerLine: "$red500",
      dangerBorder: "$red600",
      dangerBorderHover: "$red700",
      dangerPure: "$red800",
      dangerText: "$red900",
      
      successBase: "$green000",
      successBgLight: "$green100",
      successBg: "$green200",
      successBgHover: "$green300",
      successBgActive: "$green400",
      successLine: "$green500",
      successBorder: "$green600",
      successBorderHover: "$green700",
      successPure: "$green800",
      successText: "$green900",
    }
  }
});

You can also create mutable token aliases by mapping an alias to a difference color in each theme.

const { styled, theme } = createCss({
  theme: {
    colors: {
      ...slate,
      ...blue,
      ...red,
      ...green,

      // Semantic aliases

      appBackground: 'white',
      panel: "white",
      contrast: "$slate1000",
    }
  }
});

const darkTheme = theme({
  colors: {
    ...slateDark,
    ...blueDark,
    ...redDark,
    ...greenDark,
    
    appBackground: '$slate000',
    panel: "$slate200",
    contrast: "white",
  },
});
