Technically white on black is easier to read than black on white. 

yea, i have a two display setup and on the second screen my browser always glows like a lightbulb.
i just recognized the contrast while working with photoshop and 3D software on first screen.
some darker grey tones with white letters would be really nice.

edit:

yes, it always depends where you are and what device you use.
that's why a selection of several themes would be nice.

I previously said that I'd re-enable SMF themes, but now I'm thinking that this would be an awful pain. SMF themes work by duplicating a ton of code, which is difficult to maintain.

Has anyone tried writing a custom stylesheet for the forum? Is it possible to implement a dark theme that way? (How can I help?) If someone writes a good one, I'll figure out a way to let other people use it without installing any software.

I don't care  but out of simple curiosity it would be fun to see this forum in any shape other than this old-fashioned one. I doubt they will do it though -people asking for avatars back for almost 3 months now- lol.

It does look dated, but I don't really mind it. A dark theme could be much better though.

Bright themes and white background against black text always bother me, don't ask me why, but I find colour and darkness help a lot, they also actually help a lot when I look at code or other data, damn left brain thinkers and their plain themes >_<

All that does is change the colour of the taskbars, noob

heh, i've seen it live...funtime 
iirc it was possible via avatar pic upload function.

coming from graphic background i thought inverting/changing colours via code wouldn't be such a big problem.
but as theymos described it i suppose it could increase risk for hacks in the future.
