When you edit a color set, some of the options do not show you what the current color is set at. For example the Strongs Nested Background shows like this:
Strongs Nested Background -...

The problem comes when you set a custom color (like #A374B6) and want to try something else. If you want to go back to what you had it set at before there is no way to know what it was set at because it's not displayed on either Edit Color Set page or the Choose Color page.

Thanks
