 :mod:`colorsys` --- Conversions between color systems
 =====================================================
 
 .. module:: colorsys
    :synopsis: Conversion functions between RGB and other color systems.
 .. sectionauthor:: David Ascher <da@python.net>
 
 
 The :mod:`colorsys` module defines bidirectional conversions of color values
 between colors expressed in the RGB (Red Green Blue) color space used in
 computer monitors and three other coordinate systems: YIQ, HLS (Hue Lightness
 Saturation) and HSV (Hue Saturation Value).  Coordinates in all of these color
 spaces are floating point values.  In the YIQ space, the Y coordinate is between
 0 and 1, but the I and Q coordinates can be positive or negative.  In all other
 spaces, the coordinates are all between 0 and 1.

 The :mod:`colorsys` module defines the following functions:
 
 
 .. function:: rgb_to_yiq(r, g, b)
 
    Convert the color from RGB coordinates to YIQ coordinates.
 
 
 .. function:: yiq_to_rgb(y, i, q)
 
    Convert the color from YIQ coordinates to RGB coordinates.

 .. function:: hsv_to_rgb(h, s, v)
 
    Convert the color from HSV coordinates to RGB coordinates.
 
 Example::
 
    >>> import colorsys
    >>> colorsys.rgb_to_hsv(.3, .4, .2)
    (0.25, 0.5, 0.4)
    >>> colorsys.hsv_to_rgb(0.25, 0.5, 0.4)
