Amber Glass Phosphor

Amber Glass Phosphor is a dark, CRT-inspired theme for Obsidian. It is intended to bring my vision of a retro-futuristic interface to Obsidian while remaining easy on the eyes and helping with concentration. Multicolored headings make navigation quicker. Amber Glass Phosphor preview

Installation

Manual installation

  1. Create a folder named Amber Glass Phosphor inside your vault's .obsidian/themes directory.
  2. Copy theme.css and manifest.json into that folder.
  3. Open Settings → Appearance → Themes in Obsidian.
  4. Select Amber Glass Phosphor.

Community Themes

Once the theme is accepted into the Obsidian Community directory, it can be installed through Settings → Appearance → Themes → Manage.

Style Settings

The optional Style Settings community plugin exposes the theme's built-in controls. After enabling the plugin, open Settings → Style Settings → Amber Glass Phosphor.

Available controls:

  • Phosphor palette: Amber, Green, Blue, or White.
  • Disable CRT overlay: Removes scanlines and the edge vignette.
  • Disable text glow: Removes glow while retaining the selected palette.

Amber remains the default when Style Settings is not installed.

Mermaid flowcharts and sequence diagrams follow the selected phosphor palette automatically in Reading view, Live Preview, and PDF export. Chart series retain their distinct colors. The legacy renderer uses scoped selector specificity and palette variables; explicit inline diagram styles take precedence. Pele styling tokens are included for Obsidian 1.15+, but native 1.15 testing is pending.
