Yes you can do that ! In my first reply on this thread I gave you a piece of
code which build a #RRGGBB string (for example "#0000FF" is a
well-understood synonym of "green") and use it to fill the cell background.
It's also very easy to build this string from RGB integers using
Printf.sprintf :

let string_of_rgb = Printf.sprintf "#%02x%02x%02x"
let rgb_of_string s = Scanf.sscanf s "#%2x%2x%2x" (fun r g b -> r, g, b)

But obviously you have to use "background" instead of "background-gdk" when
setting the corresponding attribute. For instance :

view_column#add_attribute cell_text "background" bg_color

Hope this helps,
Eddy
