hi G_ M,
"winfo rgb ." is Tk's color name to rgb converter (for the root window's colormap). Since it fails if given an empty string, it should either be wrapped in a catch clause, or in a test, like this:
query set cl [tk_chooseColor] .: if .($cl != "".) .(winfo rgb . $cl.)
The tot's output is then a list of three 16-bit intensities, so they would probably need to be unpacked, and quantized with / 256 -> int.
