While I acknowledge that some of the spaces below should be called systems
to be technically correct, they still will be called spaces here, because
the main goal of this software is seamless interoperabilitiy between them.


=head2 RGB

... is the default color space of this CPAN module. It is used
by most computer hardware like monitors and follows the logic of additive
color mixing as produced by an overlay of three colored light beams.
The sum of all colors will be white, as in opposite to subtractive mixing.
Its is a completely Cartesian (Euclidean) 3D space and thus a RGB tuple
consists of three integer values:

B<red> (short B<r>) range: 0 .. 255, B<green> (short B<g>) range: 0 .. 255
and B<blue> (short B<b>) range: 0 .. 255.
A higher value means a stronger beam of that base color flows into the mix
above a black background, so that black is (0,0,0), white (255,255,255)
and a pure red (fully saturated color) is (255, 0, 0). The space can also
be addressed under its alias name: B<sRGB>(standard RGB).
