color-tools is a Ruby library to provide RGB, CMYK, and other colourspace support to applications that require it. It also provides 152 named RGB colours. It offers 152 named RGB colours (184 with spelling variations) that are commonly supported and used in HTML, SVG, and X11 applications. A technique for generating a monochromatic contrasting palette is also included.
Version 1.3 offers significant enhancements over color-tools 1.2, and a plan for an incompatible change to the library.
Colours that were defined in the Color namespace (e.g., Color::Red, Color::AliceBlue) are now defined in Color::RGB (e.g., Color::RGB::Red, Color::RGB::AliceBlue). They are added back to the Color namespace on the first use of the old colours and a warning is printed. In version 1.4, this warning will be printed on every use of the old colours. In version 1.5, the backwards compatible support for colours like Color::Red will be removed completely.
A CSS colour name module has been added. It is based on the Color::RGB predefined colours. It is called with “Color::CSS”. The provided colour name will be looked up ignoring case so that “DarkSalmon” and “darksalmon” (and :darksalmon) are the same value. This makes it easier on web or SVG developers who wish to be able to manipulate a colour based on a CSS colour name.
A new predefined colour namespace has been added for RGB metallic colours (Color::Metallic, in color/rgb/metallic), suggested by Jim Freeze <[email protected]>.
A new colour space, Color::HSL (hue, saturation, and luminosity) has been added with some helper methods to Color::RGB for colour manipulation.
Added unit tests and fixed various little bugs.
