-The \module{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 \module{colorsys} module defines the following functions:
-
-\begin{funcdesc}{rgb_to_yiq}{r, g, b}
-Convert the color from RGB coordinates to YIQ coordinates.
-\end{funcdesc}
-
-\begin{funcdesc}{yiq_to_rgb}{y, i, q}
-Convert the color from YIQ coordinates to RGB coordinates.
-\end{funcdesc}
-
-\begin{funcdesc}{rgb_to_hls}{r, g, b}
-Convert the color from RGB coordinates to HLS coordinates.
-\end{funcdesc}
-
-\begin{funcdesc}{hls_to_rgb}{h, l, s}
-Convert the color from HLS coordinates to RGB coordinates.
-\end{funcdesc}
-
-\begin{funcdesc}{rgb_to_hsv}{r, g, b}
-Convert the color from RGB coordinates to HSV coordinates.
-\end{funcdesc}
-
-\begin{funcdesc}{hsv_to_rgb}{h, s, v}
-Convert the color from HSV coordinates to RGB coordinates.
-\end{funcdesc}
-
-Example:
-
-\begin{verbatim}
->>> 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)
-(0.3, 0.4, 0.2)
-\end{verbatim}
