Simple color conversion library based on simplicity and stability
Create a new instance of the Colr class
// create a empty instance
var colr = new Colr();
// create from hex
var colr = Colr.fromHex('#abc123');
// create from rgb
var colr = Colr.fromRgb(20, 30, 40);
var colr = Colr.fromRgbArray([20, 30, 40]);
var colr = Colr.fromRgbObject({r:20, g:30, b:40});
// create from hsl
var colr = Colr.fromHsl(320, 20, 90);
var colr = Colr.fromHslArray([320, 20, 90]);
var colr = Colr.fromHslObject({h:320, s:20, l:90});
// create from grayscale
var colr = Colr.fromGrayscale(128);Change the color of an existing Colr instance.
All methods return the colr instance and can be chained.
var colr = new Colr();
// import from hex
colr.fromHex('#abc123');
// import from rgb
colr.fromRgb(20, 30, 40);
colr.fromRgbArray([20, 30, 40]);
colr.fromRgbObject({r:20, g:30, b:40});
// import from hsl
colr.fromHsl(320, 20, 90);
colr.fromHslArray([320, 20, 90]);
colr.fromHslObject({h:320, s:20, l:90});
// import from hsv/hsb
colr.fromHsv(30, 80, 20);
colr.fromHsvArray([30, 80, 20]);
colr.fromHsvObject({h:30, s:80, v:20});
// create from grayscale
colr.fromGrayscale(128);These are not 0 to 255 but rather:
Hue: [0, 360]
Saturation: [0, 100]
Lightness/Value: [0, 100]
Convert the color to another format
var colr = Colr().fromHex('bada55');
colr.toHex(); // "#BADA55"
colr.toRgbArray(); // [186, 218, 85]
colr.toRgbObject(); // {r:186, g:218, b:85}
colr.toRawRgbArray(); // [186, 218, 85]
colr.toRawRgbObject(); // {r:186, g:218, b:85}
colr.toHslArray(); // [74, 64, 59]
colr.toHslObject(); // {h:74, s:64, l:59}
colr.toRawHslArray(); // {74.4360902255639, 64.25120772946859, 59.411764705882355]
