I use ayu[0].

I had to sort of make my own. Each theme I tried had something that didn't work for me, the background was too light, or too dark, or I could barely see the text selection. So I settled on the Base16 Ocean Theme and tweaked with this web app https://tmtheme-editor.herokuapp.com/

Espresso Tutti is great: https://github.com/psiborg/Sublime-Packages/blob/master/Colo...

You can try out the new Celeste Theme. I personally also like Espresso Soda and Katzenmilch for lightness. There's also an XCodeish theme available or the Base16 ones are also great.

Is the Celeste theme inspired by the game?

I use Cobalt, a holdover from the TextMate days. The soda theme is okay too, but it’s a slight bit less contrasty.

I like "Soda Light 3" theme with "Visual Studio Bold" color scheme.

gruvbox may work for you (and should have 3 contrast levels)
