## Color 1.4.0 / 2007.02.11

- Merged Austin Ziegler‘s color-tools library (previously part of the Ruby PDF Tools project) with Matt Lyon‘s color library.
  - The HSL implementation from the Color class has been merged into Color::HSL. Color is a module the way it was for color-tools.
  - A thin veneer has been written to allow Color::new to return a Color::HSL instance; Color::HSL supports as many methods as possible that were previously supported by the Color class.
  - Values that were previously rounded by Color are no longer rounded; fractional values matter.
- Converted to hoe for project management.
- Moved to the next step of deprecating Color::Name values; printing a warning for each use (see the history for color-tools 1.3.0).
- Print a warning on the access of either VERSION or COLOR_TOOLS_VERSION; the version constant is now COLOR_VERSION.
- Added humanized versions of accessors (e.g., CMYK colours now have both cyan and c to access the cyan component of the colour; cyan provides the value as a percentage).
- Added CSS3 formatters for RGB, RGBA, HSL, and HSLA outputs. Note that the Color library does not yet have a way of setting alpha opacity, so the output for RGBA and HSLA are at full alpha opacity (1.0). The values are output with two decimal places.
- Applied a patch to provide simple arithmetic colour addition and subtraction to Color::GrayScale and Color::RGB. The patch was contributed by Jeremy Hinegardner <jeremy@hinegardner.org>. This patch also provides the ability to return the maximum RGB value as a grayscale colour.
- Fixed two problems reported by Jean Krohn <jb.krohn@free.fr> against color-tools relating to RGB-to-HSL and HSL-to-RGB conversion. (Color and color-tools use the same formulas, but the ordering of the calculations is slightly different with Color and did not suffer from this problem; color-tools was more sensitive to floating-point values and precision errors.)
- Fixed an issue with HSL/RGB conversions reported by Adam Johnson <adam.sven.johnson@gmail.com>.
- Added an Adobe Color swatch (Photoshop) palette reader, Color::Palette::AdobeColor (for .aco files only).

## Color 0.1.0 / 2006.08.05

- Added HSL (degree, percent, percent) interface.
- Removed RGB instance variable; color is managed internally as HSL floating point.
- Tests!

## color-tools 1.3.0

- Added new metallic colours suggested by Jim Freeze <jfn@freeze.org>. These are in the namespace Color::Metallic.
- 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.
- Added the Color::CSS module, color/css or Color::CSS that provides a name lookup of Color::RGB-namespaced constants with Color::CSS[name]. Most of these colours (which are mirrored from the Color::RGB default colours) are only "officially" recognised under the CSS3 colour module or SVG.
- Added the Color::HSL colour space and some helper utilities to Color::RGB for colour manipulation using the HSL value.
- Controlled internal value replacement to be between 0 and 1 for all colours.
- Updated Color::Palette::Gimp to more meaningfully deal with duplicate named colours. Named colours now return an array of colours.
- Indicated the plans for some methods and constants out to color-tools 2.0.
- Added unit tests and fixed a number of hidden bugs because of them.

## color-tools 1.2.0

- Changed installer from a custom-written install.rb to setup.rb 3.3.1-modified.
- Added Color::GreyScale (or Color::GrayScale).
- Added Color::YIQ. This colour definition is incomplete; it does not have conversions from YIQ to other colour spaces.

## color-tools 1.1.0

- Added color/palette/gimp to support the reading and use of GIMP color palettes.

## color-tools 1.0.0

- Initial release.
