I wanted a Hufflepuff theme for myself that wasn't just a pattern and/or brown, so I used the common room wallpaper from Pottermore.com to make a theme that would match my background. The top/tab part of the image might not be 100% aligned with the bottom part/new tab bg depending on your resolution, but I use colortab anyway so the focus here was really on the top bar and tabs themselves. Aaand I worked on this for like 2 hours and I'm just done looking at it for now so it's done :^)
