[ANN] color-tools 1.2.0

=3D color-tools README
color-tools is a Ruby library to provide RGB, CMYK, and other colour
support to applications that require it. It provides 148 named RGB
colours that are commonly supported and used in HTML, colour
manipulation operations, and a monochromatic contrasting palette
generator. Version 1.2 introduces two new colour spaces: GrayScale
(also known as GreyScale) and YIQ (NTSC).

The GreyScale colour space has been added primarily to add new
colour space support for PDF::Writer (PDF documents support CMYK,
RGB, and Grey device colour spaces). The YIQ colour space has been
promoted to a full colour class to make future colour management of
this class easier.

=3D=3D Download and Installation
Download color-tools from <http://rubyforge.org/frs/?group_id=3D81>.
Installing this package is as simple as:

% ruby setup.rb

Alternatively, you can use the RubyGem version of color-tools
available as color-tools-1.2.0.gem from the usual sources.
