Gruvbox Dark — Claude Code theme

Gruvbox began as a Vim colorscheme by Pavel Pertsev, better known as morhetz, who described the goal as 'retro groove' — earthy tones with the saturation of a seventies print ad rather than an LED. That intent survives every port: the background is a warm #282828 brown-gray, the text a cream #ebdbb2, and the accents land in brick red, mustard and olive instead of the usual laser blue and magenta.

It photographs badly and works wonderfully. In an agent session the warmth does something subtle: added lines in a diff come through as olive-green, removals as brick red, and neither carries the alarm-bell charge that high-saturation palettes give them, so reviewing a big proposed change feels less tense than it probably should. The amber accent stays loud enough that your cursor and your own prompts surface at a glance.

Upstream Gruvbox ships hard, medium and soft contrast levels; this port sits at the standard medium, the one most people mean when they say Gruvbox. It suits warm lamplight and evening rooms better than cold office fluorescents, where the browns can turn a little muddy — that mismatch, not eye strain, is usually the cue to flip over to Gruvbox Light until the sun goes down.
