`plscol0`: Set 8-bit RGB values for given cmap0 color index

`plscol0 (`	`icol0` ,
	`r` ,
	`g` ,
	`b` `)`;

Set 8-bit RGB values for given cmap0 (see the section called “Color Map0”) index. Overwrites the previous color value for the given index and, thus, does not result in any additional allocation of space for colors.

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.

Redacted form: plscol0(icol0, r, g, b)

This function is used in any example 31.
