Pinta *IS* Paint.net, just forked at an earlier stage before the latter became closed source software.

Also, is "washed and bleak" really that big of a problem for an image editor? It just doesn't matter what it looks like as long as the UI is intuitive and has the features that you need. It should also be noted that Pinta very much looks just like your overall Desktop appearance on Unix. I'm on XFCE and it's so incredibly theme integrated it looks like it's part of the system.

Personally, I really like Pinta. Biggest problem is the bugs and crashes. Wish I could use actual Paint.net though, but there's no way to use it on Linux.
