This extension maps named colors (as found in the X11 rgb.txt file) to RGB values. A single procedure is exported:
- color COLORprocedure
Returns a vector containing the red, green and blue values for the given named color value. COLOR may be a 3-element list, a 3-element vector, a string or a symbol. RGB values are in the range 0 to 255. If a name is given as argument and no color can be found, COLOR returns #f. Color name comparisons are case-insensitive.
(color "Peach Puff") ==> #(255 218 185)
