//@Module COLORSPEC Color Property Description
//@@Section HANDLE
//@@Usage
//There are a number of ways of specifying a color value for
//a color-based property.  Examples include line colors, 
//marker colors, and the like.  One option is to specify
//color as an RGB triplet
//@[
//   set(h,'color',[r,g,b])
//@]
//where @|r,g,b| are between @[0,1]@.  Alternately, you can
//use color names to specify a color.
//\begin{itemize}
//  \item @|'none'| - No color.
//  \item @|'y','yellow'| - The color @[1,1,0]@ in RGB space.
//  \item @|'m','magenta'| - The color @[1,0,1]@ in RGB space.
//  \item @|'c','cyan'| - The color @[0,1,1]@ in RGB space.
//  \item @|'r','red'| - The color @[1,0,0]@ in RGB space.
//  \item @|'g','green'| - The color @[0,1,0]@ in RGB space.
//  \item @|'b','blue'| - The color @[0,0,1]@ in RGB space.
//  \item @|'w','white'| - The color @[1,1,1]@ in RGB space.
//  \item @|'k','black'| - The color @[0,0,0]@ in RGB space.
//\end{itemize}
