Eldritch for Zed

A community-driven theme inspired by Lovecraftian horror — now with dark and light variants.

Ported from eldritch.nvim with Neovim-matched syntax highlighting across 200+ languages.

For more information, see the main Eldritch theme repository.

Variants

This release drops the old alias names and uses four clear palette names:

Variant	Appearance	Palette basis	Description
Eldritch	dark	Cthulhu	The default Cthulhu palette — vibrant accents on the sunken-depths background
Eldritch Midnight	dark	Midnight	Formerly Eldritch Deeper — vibrant Cthulhu accents on the darker Void Black background
Eldritch Abyss	dark	The Abyss	Formerly Eldritch Dark — darker background with more muted, desaturated accents
Eldritch Dusk	light	Dusk	The light version, tuned for legibility on a pale coastal background

If you used Eldritch Dark, switch to Eldritch Abyss. If you used Eldritch Deeper, switch to Eldritch Midnight.
