+
+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.
+
+More information about color spaces can be found at 
+\url{http://www.inforamp.net/\%7epoynton/ColorFAQ.html}.
+
+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}
