If it's any help to anyone, I've once made a similar AHK script for LOTRO.
It displays the color under mouse pointer in a tooltip near the pointer.
After seeing this thread, I've adapted it, so that it now displays percent of individual colors (%R, %G, %B). It's not as good as other similar programs mostly because it doesn't have any color name mappings, but it does work in full-screen mode (some experience flickering).
To use it, just run it along DDO and press shift+printscreen to activate it and shift+printscreen again to deactivate it.
Mind you, it's set to only work in DDO/LOTRO
You can download a compiled script - exe file, or if you don't trust me (and why should you, I'm a "guy" on the "internet"), you can download script or source, install autohotkey and run it/compile it for yourself (it's really easy).

source code here(so you can be sure I do not intend to grab your megahurtzs):
