I've tried a lot of themes, but this one seems to have the right combination of color, darkness, and brightness.

Some themes look good on the small sample, but once installed, don't work so well .. .they are either too bright, or too dark ... or just something seems off.

This one just looks great once installed!

I usually go for either dark or light themes, but not a combo of both. The colors complement each other so well! I was worried the lighter color would be bright, but it's not. The new tab page, however, is hard to read because both the background and font colors are dark.
