Color space in Editor UI

I used Color32 variables to store colors for a custom EditorWindow, this worked fine. Then (after just programming the EditorWindow for a while) I realized with the new (32bit) install of Unity I did, my build support plugins were gone, I was defaulted to WebPlayer, and therefore forward rendering path and gamma colorspace.

So when I changed it back to deferred and linear, all the colors in my plugin's window were off. The documentation states that color space doesn't matter in inspector / editor windows and such, but it clearly does?! Am I missing something?

Thanks in advance!
