CardinalBlue fork from original https://www.npmjs.com/package/color because they use some late Javascript syntax which interferes with Storybook and other things.
JavaScript library for immutable color conversion and manipulation with support for CSS color strings.
const color = Color('#7743CE').alpha(0.5).lighten(0.5);
console.log(color.hsl().string()); // 'hsla(262, 59%, 81%, 0.5)'
console.log(color.cmyk().round().array()); // [ 16, 25, 0, 8, 0.5 ]
console.log(color.ansi256().object()); // { ansi256: 183, alpha: 0.5 }$ npm install colorconst Color = require('color');const color = Color('rgb(255, 255, 255)')
const color = Color({r: 255, g: 255, b: 255})
const color = Color.rgb(255, 255, 255)
const color = Color.rgb([255, 255, 255])Set the values for individual channels with alpha, red, green, blue, hue, saturationl (hsl), saturationv (hsv), lightness, whiteness, blackness, cyan, magenta, yellow, black
String constructors are handled by color-string
color.hsl();Convert a color to a different space (hsl(), cmyk(), etc.).
color.object(); // {r: 255, g: 255, b: 255}Get a hash of the color value. Reflects the color's current model (see above).
color.rgb().array() // [255, 255, 255]Get an array of the values with array(). Reflects the color's current model (see above).
color.rgbNumber() // 16777215 (0xffffff)Get the rgb number value.
color.hex() // #ffffffGet the hex value.
color.red() // 255Get the value for an individual channel.
color.hsl().string() // 'hsl(320, 50%, 100%)'Calling .string() with a number rounds the numbers to that decimal place. It defaults to 1.
color.luminosity(); // 0.412The WCAG luminosity of the color. 0 is black, 1 is white.
color.contrast(Color("blue")) // 12The WCAG contrast ratio to another color, from 1 (same color) to 21 (contrast b/w white and black).
color.isLight(); // true
color.isDark(); // falseGet whether the color is "light" or "dark", useful for deciding text color.
color.negate() // rgb(0, 100, 255) -> rgb(255, 155, 0)
color.lighten(0.5) // hsl(100, 50%, 50%) -> hsl(100, 50%, 75%)
color.lighten(0.5) // hsl(100, 50%, 0) -> hsl(100, 50%, 0)
color.darken(0.5) // hsl(100, 50%, 50%) -> hsl(100, 50%, 25%)
color.darken(0.5) // hsl(100, 50%, 0) -> hsl(100, 50%, 0)
color.lightness(50) // hsl(100, 50%, 10%) -> hsl(100, 50%, 50%)
color.saturate(0.5) // hsl(100, 50%, 50%) -> hsl(100, 75%, 50%)
color.desaturate(0.5) // hsl(100, 50%, 50%) -> hsl(100, 25%, 50%)
color.grayscale() // #5CBF54 -> #969696
color.whiten(0.5) // hwb(100, 50%, 50%) -> hwb(100, 75%, 50%)
color.blacken(0.5) // hwb(100, 50%, 50%) -> hwb(100, 50%, 75%)
color.fade(0.5) // rgba(10, 10, 10, 0.8) -> rgba(10, 10, 10, 0.4)
color.opaquer(0.5) // rgba(10, 10, 10, 0.8) -> rgba(10, 10, 10, 1.0)
color.rotate(180) // hsl(60, 20%, 20%) -> hsl(240, 20%, 20%)
color.rotate(-90) // hsl(60, 20%, 20%) -> hsl(330, 20%, 20%)
color.mix(Color("yellow")) // cyan -> rgb(128, 255, 128)
color.mix(Color("yellow"), 0.3) // cyan -> rgb(77, 255, 179)
// chaining
color.green(100).grayscale().lighten(0.6)The API was inspired by color-js. Manipulation functions by CSS tools like Sass, LESS, and Stylus.
