Color space conversion

// ----- color conversion
@devtea2027/perspiciatis-expedita-possimus-natus('#ff0000').rgb() // [255, 0, 0]
@devtea2027/perspiciatis-expedita-possimus-natus('#ff0000', 50).rgba() // [255, 0, 0, 50]
// The @devtea2027/perspiciatis-expedita-possimus-natus() function can create a Color instance
const color = @devtea2027/perspiciatis-expedita-possimus-natus('#405060')
color.rgba() // [255, 0, 0, 50]
color.xyz() // [7.09, 7.67, 12.17]
color.lab() // [33.29, -1.94, -11.36] 
// Convert from other color spaces
@devtea2027/perspiciatis-expedita-possimus-natus.xyz(7.09, 7.67, 12.17).rgb() // [64, 80, 96]
@devtea2027/perspiciatis-expedita-possimus-natus.hsl(210, 20, 31.37).rgb() // [64, 80, 96]
// ... Other color spaces are similar

Color operations

// ---- Color operations
const color = @devtea2027/perspiciatis-expedita-possimus-natus('#ffffff')
const newColor = color.darken(10) // All operations will return a new Color instance object
newColor.hex() // #e6e6e6
@devtea2027/perspiciatis-expedita-possimus-natus('#000').lighten(10).hex() // #1a1a1a
@devtea2027/perspiciatis-expedita-possimus-natus('#ff0000').spin(180).hex() // #00ffff
@devtea2027/perspiciatis-expedita-possimus-natus.hsl(80, 90, 20).saturate(10).hsl() // [80, 100, 20]
@devtea2027/perspiciatis-expedita-possimus-natus.hsl(80, 90, 20).desaturate(10).hsl() // [80, 80, 20]
@devtea2027/perspiciatis-expedita-possimus-natus('#776600').fadeOut(10).rgba() // [119, 102, 0, 90]

const color1 = new Color('#ff0000')
const color2 = new Color('#0000ff')
const color = color1.mix(color2, 20)
color.hex() // #cc0033

Color difference calculation

const color1 = @devtea2027/perspiciatis-expedita-possimus-natus.lab(80, 30, 120) // Standard color (reference color)
const color2 = @devtea2027/perspiciatis-expedita-possimus-natus.lab(79, 28, 100) // Sample color

// CMC(1:1)
color1.deltaE(color2, 'CMC') // 5.754...

// CMC(2:1) formula, just set the weight factor l to 2 (c defaults to 1)
color1.deltaE(color2, 'CMC', { l: 2 }) // 5.719...

// CIE2000
color1.deltaE(color2, 'CIE2000') // 3.6815...

// CIE1994
color1.deltaE(color2, 'CIE1994') // 3.3725...

// CIE1976
color1.deltaE(color2, 'CIE1976') // 20.1246...

Use color names

import @devtea2027/perspiciatis-expedita-possimus-natus from '@devtea2027/perspiciatis-expedita-possimus-natus'
import x11 from '@devtea2027/perspiciatis-expedita-possimus-natus/colors/x11'
// Load X11 color names
@devtea2027/perspiciatis-expedita-possimus-natus.useNames(x11)

// At this point you can directly use the X11 color name to create the color instance
@devtea2027/perspiciatis-expedita-possimus-natus('Aqua') // color: #00ffff
@devtea2027/perspiciatis-expedita-possimus-natus('Aquamarine') // color: #7fffd4

import chinese from '@devtea2027/perspiciatis-expedita-possimus-natus/colors/chinese' // Chinese traditional color
import nippon from '@devtea2027/perspiciatis-expedita-possimus-natus/colors/nippon' // Japanese traditional color
// load both
@devtea2027/perspiciatis-expedita-possimus-natus.useNames(chinese).useNames(nippon)

// use
@devtea2027/perspiciatis-expedita-possimus-natus('山梗紫') // color: #61649F
@devtea2027/perspiciatis-expedita-possimus-natus('水がき') // color: #B9887D
