Color.js: the missing color library

Color.js is a very thin abstraction around a color, with a few bells on.

Normal colors:

// normal colors
Color.white // => Color('ffffff')
Color.black // => Color('000000')
Color.red   // => Color('ff0000')

custom colors, with nifty query methods!

Color('00FF10').toString() // => "#00FF10"
Color('00FF10').red()      // => 0
Color('00FF10').green()    // => 255
Color('00FF10').blue()     // => 16
Color('00FF10').rgb()      // => [0, 255, 16]
Color.rgb(0, 255, 16)      // => Color('00FF10')

hsl conversion!

Color('112233').hue()  // => 149
Color('112233').sat()  // => 128
Color('112233').lum()  // => 34
Color('112233').hsl()  // => [149, 128, 34]
// NB: This conversion is pretty buggy, and the algo needs
// a look from someone who knows a thing or two about the hsl space.
Color.hsl(149, 128, 34) // => Color('112233')

TODO

• fix the hsl->rgb algo
• color transforms (e.g. myColor.lum(-20) returns a darker color)
