grim reaper × unicorn

Grimicorn

// a calm, low-fatigue color theme

Dead, dark, colorful and lively — all at once. A muted blue-gray base with soft pastel syntax, tuned over countless late nights so nothing on screen ever burns your eyes.

One palette, ported to everything I work in: VS Code, terminals, Obsidian, Claude Code & more — each in matching dark and light variants.

the color story

Eight hues,
one feeling

Nothing is saturated enough to cause fatigue. The dark variant rests on a muted blue-gray base; the light variant shifts the same roles toward ink-on-paper.

Accents follow a strict hierarchy — blue → purple → teal — and the semantic roles never drift: green is success, salmon is error, yellow is a type or a warning.
