plscol0:  Set a given color from color map0 by 8
bit RGB value 

DESCRIPTION:

	Set a given color by 8-bit RGB value for color map0 (see the PLplot
	documentation).  Overwrites the previous (default?) color value for
	the given index and, thus, does not result in any additional
	allocation of space for colors. 

SYNOPSIS:

plscol0(icol0, r, g, b)

ARGUMENTS:

    icol0 (PLINT, input) :      Color index.    Must be less than the maximum
        number of colors (which is set by default, by plscmap0n, or even
        by plscmap0). 

    r (PLINT, input) :      Unsigned 8-bit integer (0-255) representing the
        degree of red in the color. 

    g (PLINT, input) :      Unsigned 8-bit integer (0-255) representing the
        degree of green in the color. 

    b (PLINT, input) :      Unsigned 8-bit integer (0-255) representing the
        degree of blue in the color.
