I'm working with a clients website that has a purple background (similar to the purple background color in your logo) but with the actual 'Content' background being white. Because of this, TemplateToaster assumes the background is going to be purple and changes the WordPress editor(s) background to purple, to 'match' the front end.

But in this case, it doesn't help at all when my client wants to make changes (imagine your logo being black instead of white, in front of the purple background, very hard to see!).

So, my suggestion is; I wish there was a way to change the WordPress Page/Post editor(s) background color, maybe to the default white along with the themes 'suggested' background color. This option could be added in the Appearance \ Theme Options section in WordPress.

This would help me a lot! My one year of updates is about to expire, but if you implement this feature, I will renew for another year of updates.
