== Description

Color is a Ruby library to provide basic RGB, CMYK, HSL, and other colourspace

manipulation support to applications that require it. It also provides 152

named RGB colours (184 with spelling variations) that are commonly supported in

HTML, SVG, and X11 applications. A technique for generating monochromatic

contrasting palettes is also included.

The Color library performs purely mathematical manipulation of the colours

based on colour theory without reference to colour profiles (such as sRGB or

Adobe RGB). For most purposes, when working with RGB and HSL colour spaces,

this won't matter. Absolute colour spaces (like CIE L*a*b* and XYZ) and cannot

be reliably converted to relative colour spaces (like RGB) without colour

profiles.

Color 1.8 adds an alpha parameter to all #css_rgba calls, fixes a bug

exposed by new constant lookup semantics in Ruby 2, and ensures that

Color.equivalent? can only be called on Color instances.

Barring bugs introduced in this release, this (really) is the last version of

color that supports Ruby 1.8, so make sure that your gem specification is set

properly (to ~> 1.8) if that matters for your application. This

version will no longer be supported one year after the release of color 2.0.

== History

Color is the result of a project merge between color.rb 0.1.0 by

Matt Lyon and color-tools 1.3 by Austin Ziegler. Please see History.txt for

details on the changes this merge brings.

Color::Palette::MonoContrast was developed based on techniques described by

Andy “Malarkey” Clarke[1], implemented in JavaScript by Steve G. Chipman at

SlayerOffice[2] and by Patrick Fitzgerald of BarelyFitz[3] in PHP.
