Alien — an Obsidian theme

A deep-space terminal theme for Obsidian. The black of deep space, the green phosphor glow of an old CRT ship-computer, acid lime, and hazard amber — with a red alert held back for errors and unresolved links.

Palette

Token Hex Used for
Void Black #04070a Primary background
Hull #0a1014 Secondary surfaces, modals, tab strip
Bulkhead #111a1f Inputs, buttons, embedded blocks
Conduit #1d2a30 Borders, dividers
Phosphor Green #36e07a Accent, headings, links, active states
Acid Lime #b6d957 Bold text, code strings
Scanner Cyan #45cfe0 Secondary accent, italic, external links
Hazard Amber #ff9d2f Highlights, numbers, warnings
Red Alert #e8473a Errors, unresolved links, danger

H1–H3 carry the phosphor-green glow; H4–H6 fall back to scanner cyan and vapor grey so heading hierarchy stays legible at a glance.

Compatible with

  • Obsidian 1.4+
  • Default core plugins (Graph, Outline, Tags, Search, Bookmarks)
  • Light mode included (powered down — softened green + amber daylight)

Notes

  • Headings, links, tags, and the active tab glow in CRT phosphor green.
  • Code blocks use a near-black terminal background with green keywords, acid-lime strings, and amber numbers.
  • Blockquotes get a green left bar and a faint glow — the terminal "signal" motif.
  • Highlights (==text==) use hazard amber, like a warning strip.
  • Red alert is reserved for unresolved links and destructive actions, so it stays meaningful when you see it.
