Calling Sequence




name of a color.


RGB integer values of a color.


id of the color.


color returns the color id corresponding to its argument:

  • name must be the name of a known color (see color_list).

  • r, g and b must be integers between 0 and 255 corresponding to colors components red, green and blue. As usual 0 means no intensity and 255 means all the intensity of the color.

If the requested color does not exist in the current colormap it is added to the colormap. If no window exists, the color is added to the default figure colormap.

This function can be used to specify the foreground or background colors when plotting.


// using existing colors
// new colors: there are added to the colormap
e=gce(); p1=e.children(1); p2=e.children(2);
p1.foreground=color("purple"); p2.foreground=color("navy blue");
// using RGV values
