💡 Lightbulb

Philosophy

Bright actions on subtle surfaces, lit up by an intuitive palette of colors.

Lightbulb is a minimal dark theme for Visual Studio Code that intelligently illuminates items of interest, while elegantly fading away unnecessary distractions.

This is a comprehensive theme designed over many years of experimentation with my own VS Code setup, with the goal of a design that increases productivity (but is also nice to just stare at).
