Blizzard decided to remove RUNES from PowerBarColor (for whatever reason), so it was removed from Ellyb

Unfortunately, we manually list the colors to display in the color picker in their respective categories, which in turn caused the color picker to not work on Classic.

We can either manually add the color in the ColorManager, remove it from the color picker in Classic, or add checks to make sure missing colors don't entirely break the color picker. 🤔

I think we fixed this didn't we?
