At last, a theme whose colors I like, yet it remains light enough so I can read all the tabs that I may have open!
I loved some of the other themes, especially those with birds or cats, but they always came up so much darker than they looked in the list of themes when I chose them that they annoyingly obscured the lettering in tabs.
Yes, I tried going to Tools>Settings>... and way at the bottom of some page, switching from "automatic" to "light," but the themes were not affected in the least. It's disappointing.
