If you're searching for rgb levels of colors you should use uigetcolor()
instead of getcolor(). You can also have a look to
functions "name2rgb" and "rgb2name" which convert color names to rgb
levels , or "color" which convert a colormap number (= color id) to the
corresponding rgb levels.
See the example below coming from my book about scilab :
