Looking for a color picker addon

[123noob]

Hi, just as the title said, I need to find a colorpicker (with copy and paste function). I tried using the wowace updater and downloaded crayonlib and one other color lib... but for some reason none of them work, the color picker window I got in-game while having those 2 on (or 1 at a time) is still the same default color picker window. Please tell me how to fix this or where to get one mod like so.

Thanks a bunch.
