What are the best color themes for text editors?

Awesome color variation if you want that vibrant look for your syntax.

Color scheme I keep gravitating to.

Color palette is great with high contrasty colors.

This is my secondary theme for Spacemacs. I usually use Noctilux, but when I need a light theme due to glare (or when switching focus among other light windows), I switch to Leuven. It reminds me of the default themes of the old Java IDEs I used in school, so it feels familiar.

This is my primary theme for Spacemacs. It's based on Light Table's default theme. But I did make one tweak: I changed the very-dark gray background to pure black for better contrast.

I prefer Noctilux, but Wombat has a very similar feel and is more widely available.

Very pleasant to my eyes. Been using this color scheme for as long as I can remember, stuck with it through different editors (Sublime, VS Code, vim) even after trying out others.

The theme has a very clean and modern look to it.

Looks nice and does not burden your eyes at all.

I love the theme and really love the customization available.
