The :mod:`colortools` defines a :cls:`Color` object that can be used to
represent and manipulate colors in various contexts. It was created with the
:mod:`FGAme` game engine, but it can also be used in other contexts such as
arts and web applications.
Colors can be initialized from the RGB/RGBA components, in which each component
is in the 0-255 range.
>>> w1 = Color(255, 255, 255)
>>> w2 = Color(255, 255, 255, 255)
>>> w1 == w2
The constructor also accepts color names, hex strings or hex numbers.
>>> Color('white') == Color('#FFF') == Color(0xffffff) == Color(255, 255, 255)
All names in CSS3.0 are accepted (see the complete list `here<http://www.w3.org/TR/css3-color/#svg-color>`).
It is worth noting that although the *G* in RGB stands for green, the color
with a full green value is called *lime*, while "green" is **#008000** rather than
Usage and API
Color objects are immutable and behave like a tuple of 4 values.
[0, 80, 0, 255]
It also exposes several different representations of a color using the
>>> blue = Color('blue')
(255, 0, 0)
(1.0, 0.0, 0.0)
Color objects also implement a few useful transformations
>>> blue.darken(0.1) # darken by 10%
Color(229, 0, 0)
