Jaslm and I worked on this together. The standard ColorPickerFrame that is used to select colors is blizz's pre-configured ColorSelect frame. Jaslm's ColorPickerPlus hooks several of the functions in ColorPickerFrame to add features. The reported bug was introduced fairly recently and was reported by users of both the built-in color picker and ColorPickerPlus. We instrumented the code to determine that internal r, g, b values are correctly set with SetColorRGB (by checking what is returned with GetColorRGB) but the displayed color is not updated properly in blizz's ColorPickerFrame. In any case, the bug is demonstrated with the built-in color picker no longer coming up showing the color it is supposed to edit.

I'll look at the ColorPickerFrame.xml code to see if any changes were made in 7.1.
