I have a lot of trouble with with my eyes. I can't have it too bright, too contrasty, too dark, not enough contrast..... and on and on. I am picky because I'm an artist and love color, I love good design, and yet I am really practical -- I want plain, rather than busy. Call me Goldilocks, but I needed something "just right."
I used to love the old classic Windows color schemes. They were so well done, I rarely found a need to change anything. In any case, I'd been hunting for a decent theme for hours and finally found this one. I feel so relieved!!. Perfection. Thanks!

Ideal. Just what I was looking for - feels like Firefox, not too dark, not too pale. Thank you!

These are really good. The menus and tabs look really good. I recommend it.
