Color is a Ruby library to provide RGB, CMYK, HSL, and other color space manipulation support to applications that require it. It provides optional named RGB colors that are commonly supported in HTML, SVG, and X11 applications. The Color library performs purely mathematical manipulation of the colors based on color theory without reference to device color profiles (such as sRGB or Adobe RGB). For most purposes, when working with RGB and HSL color spaces, this won't matter. Absolute color spaces (like CIE LAB and CIE XYZ) cannot be reliably converted to relative color spaces (like RGB) without color profiles. When necessary for conversions, Color provides D65 and D50 reference white values in Color::XYZ. Color 2.0 is a major release, dropping support for all versions of Ruby prior to 3.2 as well as removing or renaming a number of features. The main breaking changes are: - Color classes are immutable Data objects; they are no longer mutable. - RGB named colors are no longer loaded on gem startup, but must be required explicitly (this is _not_ done via `autoload` because there are more than 100 named colors with spelling variations) with `require "color/rgb/colors"`. - Color palettes have been removed. - `Color::CSS` and `Color::CSS#[]` have been removed.

ZenTest provides 4 different tools: zentest, unit_diff, autotest, and multiruby. zentest scans your target and unit-test code and writes your missing code based on simple naming rules, enabling XP at a much quicker pace. zentest only works with Ruby and Minitest or Test::Unit. There is enough evidence to show that this is still proving useful to users, so it stays. unit_diff is a command-line filter to diff expected results from actual results and allow you to quickly see exactly what is wrong. Do note that minitest 2.2+ provides an enhanced assert_equal obviating the need for unit_diff autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. multiruby runs anything you want on multiple versions of ruby. Great for compatibility checking! Use multiruby_setup to manage your installed versions. *NOTE:* The next major release of zentest will not include autotest (use minitest-autotest instead) and multiruby will use rbenv / ruby-build for version management.
