Yes, true.  I was thinking that since these frameworks already have 
color-picker features, they are simply a matter of a few lines.

I installed gcolor2 and this works nicely, thanks.  In addition to the 
eye-dropper, it also goes one step more in convenience by combining the 
RGB into a ready-made triplet #rrggbb that can be easily selected, 
copied and pasted.
