Like I said before, I'm down with any color as long as it's easy on the eyes. My eyes are really sensitive to bright colors. Especially reading screens where the lettering is hard to see/nearly the same color as the BG (no contrast).
you know u can probably edit the css for the site yourself so that you wont need to spend any money right? Also you can enable multiple themes at once and let people choose whichever one they prefer. im pretty sure thats standard with vb.
