Gruber Darker for Visual Studio

A native Visual Studio dark theme with muted UI chrome and a warm, readable syntax palette — ported from the Gruber Darker lineage that runs through Emacs and BBEdit.

About

Gruber Darker for Visual Studio brings a long-running color scheme lineage natively into the VS shell — editor, tool windows, and chrome alike — rather than just recoloring the text editor.

The lineage:

1. Gruber Dark — the original BBEdit colour scheme by John Gruber.
2. Gruber Darker — a darker Emacs port of Gruber Dark, originally by Jason Blevins and now maintained by Alexey Kutepov (rexim).
3. This extension — a Visual Studio port of the Gruber Darker palette, mapped across the full set of VS editor, language service, and environment colour tokens (not just the code editor).

The palette itself (bg, fg, red, green, yellow, brown, niagara, wisteria, …) is carried over unchanged from gruber-darker-theme.el; what this project adds is the mapping of those roles onto Visual Studio's much larger token surface.

Features

• Full-shell theming: editor surface, language service classifications, tool windows, and environment chrome all resolve to the same Gruber Darker palette, not just syntax colours.
• Warm, low-saturation syntax highlighting: comments in brown, strings in green, keywords in yellow, types in a muted quartz grey.
• Consistent diagnostic colouring for errors, warnings, added/removed/changed state, and debugger execution markers.
