color

returns the color id of a color

Calling Sequence

id=color(name)
id=color(r,g,b)

Arguments

name

name of a color.

r,g,b

RGB integer values of a color.

id

id of the color.

Description

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.

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

Examples

x=linspace(-2*%pi,2*%pi,100)';
// using existing colors
plot2d(x,[sin(x),cos(x)],style=[color("red"),color("green")]);
// 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
p1.foreground=color(255,128,128);
