Etna Theme for OpenCode

The premium Codigrate Etna theme for OpenCode. Add it to your cart, pay once, download it right away; install steps included.

Inspired by Mount Etna's nighttime eruptions, this dark theme builds on an ashen basalt grey base and layers in the incandescent reds, oranges, and golds of molten lava. The near-neutral charcoal surface keeps long sessions calm, while the warm lava accents draw the eye to what matters.

  3. In OpenCode, type /theme and pick the theme from the list, for example codigrate-london.
  4. Your terminal needs 24-bit color: run echo $COLORTERM and look for truecolor or 24bit.

  • Anatomy of a Dark Theme: Etna: Anatomy of Etna, a dark IDE theme: basalt and volcanic ash for the frame, lava rose keywords, sulfur gold members and strings the grey of fresh ash.
  • Value: How Colors Get Vivid: Value is the V in HSV, the brightness dial that tops out at the pure color, not white. How it differs from lightness, and why designers reach for it.
