The palette editor needs to be enlarged to fill in the red background, so it's not so painful to the eyes! I have to switch to small mode to edit my palettes and switch back to the large mode when i'm done.
Large Mode Palette Editor
Is it possible for the devs to enlarge the palette editor dialog to fill the screen in large mode?
Well, I got it to make the background black. I'm not certain it's consistent, but it seems to be.
