Etna Theme for Slack

The premium Codigrate Etna theme for Slack. 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.
