Operator Dark

A calm, navy-charcoal editor theme designed for long coding sessions. Desaturated, contrast-first syntax with restrained teal and amber accents.

Why this theme

Three rules drive every color choice.

• Contrast before saturation. Surfaces stay quiet — the syntax doesn't fight the layout for attention.
• Restraint before novelty. Two accents do the work — teal for UI state, amber for strings.
• Colorblind-safe pairings. No state in the theme — add vs delete, success vs error, modified vs untracked — relies on red vs green alone. Every meaningful pair is verified across deuteranopia, protanopia, and tritanopia.

Install

1. Open VS Code → Extensions (Ctrl+Shift+X).
2. Search for Operator Dark.
3. Install, then F1 → Preferences: Color Theme → Operator Dark.

Highlights

• One theme, no variants — one well-tuned palette instead of three half-tuned ones.
• Workbench + TextMate + semantic tokens — full three-layer coverage, no scope-suffix surprises.
• Theme-only diffs — teal-green adds and warm coral deletes, no companion extension required.
• AL / Business Central tuning — sage-green fields, properties, enum members, and quoted identifiers (e.g. ::"All Customers" highlights correctly).
• Custom bracket pair colors — teal → amber → purple → type-blue.
• Italic comments only.
• Markdown preview styled to match — body surfaces, headings, links, tables, blockquotes, and code-block chrome track the theme via VS Code CSS variables.
