colorjs
colorjs provides simple API that may be used to create colors (RGBA, HSVA, HSLA) and perform various color related operations (conversions and such).
Examples
Making red (#FF0000)
color.rgba('red');
color.rgba('#FF0000');
color.rgba('FF0000');
color.hsva('red');
color.hsva('#FF0000');
color.hsva('FF0000');
color.hsla('red');
color.hsla('#FF0000');
color.hsla('FF0000');
color.rgba({r: 1});
color.hsva({s: 1, v: 1});
color.rgba().r(1);
color.hsva().s(1).v(1);
Getter/setter notation
var c = color.rgba('red');
c.r(0.5);
c.r(); // should return 0.5
toArray
var c = color.rgba('red');
c.toArray(); // [1, 0, 0, 1]
toHex
var c = color.rgba('red');
c.toHex(); // 'ff0000'
toCSS
var c = color.rgba('red');
c.toCSS(); // 'rgb(255,0,0)'
c.a(0.5);
c.toCSS(); // 'rgba(255,0,0,0.5)'
Chaining
var c = color.rgba('red');
c.r(0.5).b(0.5); // chains
c.toArray(); // [0.5, 0.5, 0, 1]
Bounds
var c = color.hsva({h: 10, s: -10, v: 5, a: -2});
c.toArray(); // [1, 0, 1, 0]
Type conversions
var c1 = color.rgba('red');
var c2 = color.hsva(c1);
c2.toArray(); // [0, 1, 1, 1]
