Get Color Indices

get_color_indices in combination with get_color_tuple will retrieve the RGB values for colors.
print cmd.get_color_indices()

will retrieve the Pymol color names and corresponding internal color indices. The Pymol names can be used to designate color for objects, see Color. To retrieve a single index for a specific color name, use get_color_index instead.

print cmd.get_color_tuple(index-number)
will retrieve individual RGB components when index-number is replaced with one of the color indices from above.

The color index, an integer, gets returned when color is returned while employing Iterate. You can thus use the get_color_tuple command above to convert that to RGB color values if you need to use the colors outside Pymol.

Tangentially related is the fact you can name additional colors,

set_color color-name, [r,b,g]

will create a new color that will appear in the GUI list. From the open-source ..→
