16 themes · terminals & editors

Light, measured for tired eyes.

Candela is a set of 16 color themes for terminals and editors, tuned for eye-strain comfort.

For people who like dark mode but can't use it comfortably — prescription lenses, astigmatism, glare sensitivity, plain eye strain. Off-white paper (never pure white), dark-gray ink (never pure black), and desaturated pastel syntax keep the calm, low-contrast feel without the glare. 14 light themes and 2 dark companions tuned to the same contrast rules.

How it works

Every palette is authored in one JSON source of truth, then generated into terminal and editor formats — iTerm2, Alacritty, Kitty, WezTerm, Ghostty, VS Code, JetBrains, Zed, Sublime, Neovim, and Helix.

Browse all 16 in the gallery, tweak one in the Theme Editor, or derive your own in the Theme Builder.
