Umbra

Umbra is a dark theme extension for Zed with two variants:

• Umbra Mono - monochrome syntax with minimal visual noise
• Umbra Color - the same base UI palette with colorized syntax highlighting

Both variants preserve semantic UI accents for diagnostics, git changes, and editor states.

Theme Variants

Umbra Mono

Monochrome syntax built around contrast and hierarchy.

Umbra Color

Colorized syntax for better token recognition while keeping Umbra's dark mood.

Semantic Accents

UI semantic colors are intentionally subtle and consistent across both variants:

• Green - created/added lines, success states
• Red - errors, deleted lines
• Amber - warnings
• Purple - conflicts, predictive/AI states
• Blue-gray - informational and comment-like contexts
