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

First, make sure you have GemCutter set up:

  gem install gemcutter
  gem tumble

Then, grab the gem:

  gem install slippyd-colorist

Last, add the requirement to your project and enjoy!

  # in environment.rb, after "Rails::Initializer.run do |config|":
  config.gem 'slippyd-colorist', :lib => false, :version => '0.0.5'

  # in any class or module that you want to use Colorist:
  include Colorist
