Ef Maris Dark

An Obsidian port of ef-maris-dark from Protesilaos Stavrou's ef-themes for Emacs — "legible dark marine theme with blue, cyan, and green colors."

Dark mode only. In light mode Obsidian falls back to its default theme.

What it covers

The port maps the upstream palette onto Obsidian's CSS variables, so the colors carry across editor and UI alike:

  • Headings use the ef-themes rainbow mapping (rainbow-0 through rainbow-6), with the inline title in green-cooler.
  • Syntax highlighting in code blocks follows the upstream faces — keyword in blue-warmer, string in cyan-cooler, comment in red-faint, and so on. Inline code uses prose-code (cyan).
  • Editor accents match their Emacs counterparts: the active line is bg-hl-line, selections are bg-region, search matches are bg-yellow-intense, and the caret is cursor.
  • Chrome — status bar, tabs, scrollbars, graph view, callouts, tables and properties — is derived from the same ramp.

Every variable is annotated with the upstream face name it came from, so the CSS doubles as a mapping table if you want to port another ef-theme.

Install

From Obsidian: Settings → Appearance → Themes → Manage, then search for "Ef Maris Dark".

Manually: copy theme.css and manifest.json into <vault>/.obsidian/themes/Ef Maris Dark/, then select the theme under Settings → Appearance.

A note on the gutter

The theme takes editor gutters (line numbers, and sign columns added by plugins like Vim Motions) out of the layout flow so they don't push note content to the right of the Properties block. This mirrors what the Minimal theme does. It is the one layout rule here; everything else is color.

Credit

The palette is the work of Protesilaos Stavrou and belongs to the ef-themes project, which is licensed GPL-3.0. This port carries the same license. It is not an official ef-themes release, and the upstream authors are not responsible for it.
