Vellum — An Obsidian Theme

Write like you're inscribing on ancient parchment. Read like you're holding a manuscript under moonlight.

A sophisticated dual-mode theme for Obsidian — warm Vanilla Parchment for daylight writing, calm Charcoal Grey for late-night sessions.


Features

  • Playfair Display headings — elegant, editorial, timeless
  • Charm body text — calligraphic, warm, a joy to read
  • Sepia toggle — Switch light theme font from Navy Blue → Warm Brown (old scroll feel)
  • Ultra minimal UI — Everything hidden until you need it
  • Style Settings support — Adjust font size, line height, content width, accent colors, and more — no CSS knowledge needed
  • WCAG AA accessible — All color combos tested (6.48:1 contrast ratio on dark mode)
