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.

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")
