Dark theme with highly visible active tab. Also has some elements with lower contrast for improved visibility.
Double Yellow means don't pass ... on this theme. Do you like dark themes but you can never tell which is the active tab? Check out Double Yellow! The active tab is a bright, pleasing yellow, so you can spot it quickly.
Supports omnibox colors added in Chrome 80!
In this theme, background tabs are dark gray rather than black, which makes the loading spinner easier to see. The omnibox is also dark yellow rather than black, which I think is a bit more aesthetically pleasing.
