Colorist
Colorist is a library built to handle the conversion, comparison, and manipulation of colors in Ruby projects with an emphasis on W3C standards and CSS-style hex notation. See the Color class for additional details on the available methods.
Example
require 'colorist'
include Colorist
gray = Color.new(0x333333)
gray + gray # => #<Color #666666>
gray - "#333" # => #<Color #000000>
gray.invert # => #<Color #cccccc>
gray.brightness # => 0.2
gray.contrast_with("#f00")
Installation
