Oh, wait, what? Those squares? That's how this works?
...
Too complicated for me, apparently.
I'll just go over there now...
So, yeah.
It might not hurt if the font were bigger... I've been using 110% zoom (on Chrome) even with the old theme. (I'm afraid of the day when i'll have to use 1080p display, helping my brother with his laptop was difficult thanks the resolution.)
Have the green selected right now. The colored text could be a tad darker, or the background should be darker, slightly more contrast anyway. Also not a fan of the shade of green (jade?) on those horizontal bars, slightly darker might be better.
Steel's colored text needs even more contrast, or just having darker yellow would be good. Same with red, and blue... and probably everything else.
EDIT Corrected to green. And did the font just change?
