• default (optional): If set to true, uses the default configuration. Default is true.

Default Options

The defaultOptions object represents the default configuration for the package:

const defaultOptions: DefaultOptions = {
  suffixMultiplier: 100,
  variablePrefix: undefined,
  contrast: true,
  complement: true,
  classification: {
    light: "#FFFFFF",
    dark: "#000000",
  },
  steps: 100,
  default: true,
};

generateConfig()

const extendedColors = generateConfig(colorNames, options);

The generateConfig function takes the following parameters:

• colorNames: An array of color names or a single color name.
• options (optional): An object of options that allows you to customize the generated colors. The available options are suffixMultiplier (default: 100), which determines the suffix used to generate variables names (e.g [1, 10, 100]) and variablePrefix (default: undefined), which determines the prefix for the css variable name, none by default.

The function returns a config object for Tailwind CSS with the specified color names and their respective tints.

generateStyleVariables()

const variables = generateStyleVariables(colorParams, options);

The generateStyleVariables function takes the following parameters:

• colorParams: An array of color params or a single color params including a color (hex) and a name.
• options (optional): An object of options that allows you to customize the generated colors. The available options are suffixMultiplier (default: 100), which determines the suffix used to generate variables names (e.g [1, 10, 100]) and variablePrefix (default: undefined), which determines the prefix for the css variable name, none by default.

Example

Extend your tailwind config

tailwind.config.js

/** @type {import('tailwindcss').Config} */
import { generateConfig } from "tailwindcss-custom-colors";

const extendedColors = generateConfig(["primary", "secondary"]);

module.exports = {
  content: ["./src/**/*.{index,vue,js,ts,jsx,tsx}"],
  theme: {
    extend: {
      colors: extendedColors,
    },
  },
  plugins: [],
};

Output for extendedColors:

{
  "primary": {
    "100": "rgb(var(--primary-100) / <alpha-value>)",
    "200": "rgb(var(--primary-200) / <alpha-value>)",

    "600": "rgb(var(--primary-600) / <alpha-value>)",
    "700": "rgb(var(--primary-700) / <alpha-value>)",
    "800": "rgb(var(--primary-800) / <alpha-value>)",
    "900": "rgb(var(--primary-900) / <alpha-value>)",
    "DEFAULT": "rgb(var(--primary) / <alpha-value>)",
    "contrast": "rgb(var(--primary-contrast) / <alpha-value>)",
    "complement": "rgb(var(--primary-complement) / <alpha-value>)"
  },
  "secondary": {
    "100": "rgb(var(--secondary-100) / <alpha-value>)",
    "200": "rgb(var(--secondary-200) / <alpha-value>)",
    "300": "rgb(var(--secondary-300) / <alpha-value>)",
    "400": "rgb(var(--secondary-400) / <alpha-value>)",
    "500": "rgb(var(--secondary-500) / <alpha-value>)",
    "600": "rgb(var(--secondary-600) / <alpha-value>)",
    "700": "rgb(var(--secondary-700) / <alpha-value>)",
    "800": "rgb(var(--secondary-800) / <alpha-value>)",
    "900": "rgb(var(--secondary-900) / <alpha-value>)",
    "DEFAULT": "rgb(var(--secondary) / <alpha-value>)",
    "contrast": "rgb(var(--secondary-contrast) / <alpha-value>)",
    "complement": "rgb(var(--secondary-complement) / <alpha-value>)"
