loganzartman / Color.js
Last active January 24, 2017 05:59
A standalone library for working with color in Javascript.
/**
* Represents a color that can be expressed as an RGB value.
* RGB values are in the range 0 ~ 255 (rounded for display).
* HSL values are in the range 0 ~ 1.
* A color can be constructed using any of the following:
* - No arguments; will be interpreted as black
* - A single integer representing a packed RGB value
* - Three integers or floats representing RGB or HSL values (depending on Color.DEFAULT_MODE)
* - A hex #NNNNNN color string
* - A canvas2d/CSS rgb(n,n,n) or hsl(n,n%,n%) color string
