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  :

-->//red =  rgb color (255,0,0)

-->rgb=name2rgb("red")
 rgb  =

    255.    0.    0.

-->rgb2name(rgb)
 ans  =

!red   !
!      !
!red1  !

-->// red = color numver 5

-->color("red")
 ans  =

    5.

-->color(rgb(1),rgb(2),rgb(3))
 ans  =

    5.
