Dark Knight — Gotham Dark Theme for Visual Studio
A premium, cinematic Batman-inspired dark theme for Microsoft Visual Studio 2022.
Featuring a distinctive Batcave workstation aesthetic with elegant golden panel borders, professional C# and .NET syntax highlighting, and an optional non-intrusive editor background system.
Overview
Dark Knight transforms Visual Studio 2022 into a sophisticated Batcave workstation. Engineered for professional .NET developers, it replaces standard high-glare surfaces with a balanced near-black charcoal foundation (#101216), deep graphite tool windows (#171C25), muted antique gold panel borders (#69552B), bright gold active accents (#FFC94A), and electric Gotham blue highlights (#4D8DCC).
This is a genuine Microsoft Visual Studio Extension (VSIX) built with the official Visual Studio SDK, not a Visual Studio Code port. It delivers:
- Elegant Golden Panel Borders: Restrained 1-pixel antique gold borders around Solution Explorer, Properties, Git Changes, GitHub Copilot Chat, Error List, Output window, and Terminal panels.
- Full IDE Theme Coverage: 54 Visual Studio categories styled natively via compiled
.pkgdef and .vstheme resources with fallback inheritance.
- Professional C# & .NET Roslyn Highlighting: Accessible semantic colorization meeting WCAG 2.1 AA/AAA contrast ratios.
- Optional MEF Editor Background System: Subtle Batcave workstation watermarks rendered behind code via official WPF editor APIs (
IWpfTextViewCreationListener), with adjustable opacity and a dark tint shield.
- Interactive Settings Interface: Full configuration panel hosted under Tools > Options > Dark Knight Theme > Batcave Background and as a dedicated dockable Tool Window.
- Original UI Assets: Bespoke nocturnal vigilante branding, metallic gold emblem, status bar icon, tool window icon, surface texture, and HD concept art backgrounds.
