Gasrulle Theme
A curated theme pack for Visual Studio Code — featuring faithfully ported IDE themes and original creations.

Currently Included
Rider Dark (New UI)
The modern JetBrains New UI dark theme (2023+), featuring the refined gray palette, blue accents, and updated syntax highlighting with distinct colors for functions (#56A8F5), keywords (#CF8E6D), strings (#6AAB73), and more.
Rider Dark (Darcula)
The classic JetBrains Darcula theme, featuring the iconic warm color palette with golden functions (#FFC66D), orange keywords (#CC7832), green strings (#7EA86D), and purple properties (#A885B8).
Visual Studio Dark 2019
A faithful port of the Visual Studio IDE Dark theme, with key differences from VS Code's built-in Dark+:
- Type differentiation: Structs (
#86C691), interfaces/enums (#B8D7A3), and classes (#4EC9B0) each have distinct colors
- Properties as white:
.Services, .Length, etc. render as plain text (#DCDCDC), not variable-blue
- Namespaces as white:
using System.Text shows namespaces in white, not teal
using keyword in blue: Treated as a regular keyword (#569CD6), not purple
- VS IDE string color: Pinkish
#D69D85 instead of orange #CE9178
- Comment color: Muted gray
#7A7E85 instead of olive #6A9955
- Control flow keywords: Lavender
#D8A0DF instead of purple #C586C0
Colors sourced from Roslyn VisualStudio2019.xml (MIT License).
Visual Studio Dark 2022
The updated VS 2022 shell appearance with identical syntax highlighting to VS 2019. Key visual differences:
- Unified title bar + activity bar: Both use
#1F1F1E for a seamless top chrome (vs #383838/#313131 in 2019)
- Purple accent indicators: Active tab top border, activity bar indicator, and panel title border use
#715FE7 (vs blue #0078D4)
- Gray status bar:
#424242 instead of blue #007ACC
- Updated input fields: Darker
#333337 background with #434346 border
Shell colors sourced from the Microsoft Color Value Reference and community references (best effort — no official machine-readable color file exists for VS 2022).
Visual Studio Dark 2026
The VS 2026 shell appearance built on the Fluent Design System, with identical syntax highlighting to VS 2022/2019. Key visual differences from VS 2022:
- Darker environment:
#1C1C1C environment background (vs #1F1F1E in 2022)
- Editor background:
#1C1C1C (vs #1E1E1E)
- Brighter lavender accent:
#9184EE for active indicators and focus borders (vs #715FE7)
- Fluent surface hierarchy: Sidebar/widgets use
#2C2C2C, tab strip/inputs use #282828
Shell colors sourced from VS 2026 Fluent Design System tokens documented in the Modernize Theme Colors migration guide. Syntax highlighting identical to VS 2022/2019.
Apex Ember++
An original "golden standard" dark theme synthesized from the best elements of the most popular community themes. Designed with warm pastels, accessibility research, and maximum C# semantic differentiation.
Design Philosophy — what makes this theme special:
- Night Owl — Accessibility-first: blue for functions (reading comprehension research), meaningful contrast hierarchy, muted UI chrome
- Catppuccin — Warm pastel harmony: soothing colors, balanced saturation, neither too dull nor too bright
- Tokyo Night — Semantic sophistication: rich semantic token scoping, intentionally low-contrast UI
- One Dark Pro — Clean C# scoping: well-organized type/variable differentiation
- Dracula — Vivid accent distinctiveness: every syntax role clearly separated
C# Semantic Depth (++ = Maximum):
- Every type category has a unique color: classes (
#81C8BE teal), structs (#A6D9A6 sage), interfaces (#B4BEFE lavender), enums (#EEBEBE flamingo)
- Properties (
#F4B8E4 pink) are distinct from variables (#B6BCCE foreground)
- Parameters (
#E5C890 amber) are distinct from local variables
- Control flow keywords (
#D8B0F8 italic) stand out from regular keywords (#C9A0F5)
- Static members get italic styling across all categories
- Enum members use italic to distinguish from the enum type
Apex Theme Family — four color temperatures, each with maximum C# semantic depth:
| Variant | Color Temperature | Inspiration | Key Accent |
|---------|------------------|-------------|------------|
| Ember++ | Warm pastels | Catppuccin + Night Owl warmth | #8CAAEE warm blue |
| Frost++ | Cool & modern | Tokyo Night blue-tinted | #7AA2F7 azure |
| Steel++ | Balanced neutral | One Dark Pro balance | #61AFEF clear blue |
| Neon++ | Vibrant & bold | Dracula high energy | #BD93F9 vivid purple |
| Carbon++ | Achromatic dark | Pure gray, measured saturation | #78C8F0 steel blue |
| Pastel++ | Soft pastel | Achromatic BG, chalky pastels | #8CBDC6 teal |
All five use maximum C# semantic depth (++) — every type category gets a unique color, properties are distinct from variables, parameters are distinct from locals, static members get italic styling.
Apex Pastel++ (Soft & Chalky)
An achromatic dark theme with soft, chalky pastel syntax. Pure gray backgrounds (R=G=B) paired with teal keywords, lilac functions, and amber classes — entirely different hue families from Ember. Uses a 3-band WCAG luminance strategy to maintain readability across all pastels (S≤36%).
- Keywords in pastel teal (
#8CBDC6), functions in lilac (#AA8BC1)
- Properties in pastel rose (
#E2C8CF), parameters in chartreuse (#C7D3B3)
- Five distinct type colors: classes in amber (
#D5CFB5), structs in jade (#8EBFAB), interfaces in orchid (#BB87B2), enums in periwinkle (#9393C5)
Apex Frost++ (Cool & Modern temperature)
A cool blue-tinted dark theme inspired by Tokyo Night Storm. Sleek and professional with sharp syntax against quiet chrome.
- Keywords in azure blue (
#7AA2F7), functions in cyan (#7DCFFF)
- Properties in teal-green (
#73DACA) for a cool, functional feel
- Blue-gray comments (
#535D87) blend into the cool background
Apex Steel++ (Balanced Neutral)
A neutral, balanced dark theme inspired by One Dark Pro. Professional clarity without color temperature bias.
- Keywords in purple (
#C678DD), functions in blue (#61AFEF)
- Properties in red-rose (
#E06C75), the One Dark signature
- Neutral gray comments (
#5B6270) for clean readability
Apex Neon++ (Vibrant & Bold)
A high-energy dark theme inspired by Dracula. Maximum visual intensity with vivid, saturated colors.
- Keywords in hot pink (
#FF79C6), functions in neon green (#50FA7B)
- Properties in bright orange (
#FFB86C), electric and warm
- Dracula blue-gray comments (
#566698) stay quiet while neon blazes
Apex Carbon++ (Achromatic Dark)
The only theme in the family with truly achromatic backgrounds (R=G=B). Pure graphite editor surface with zero color cast — every other Apex theme has blue or purple undertones. Syntax colors use measured saturation (25–54%) with hues evenly distributed across the color wheel for perfect temperature neutrality.
- Keywords in dusty rose (
#E68CA5), functions in steel blue (#78C8F0)
- Properties in bright salmon (
#E8A898), warm and clearly visible
- Pure gray comments (
#6E6E6E) — achromatic scaffolding for measured syntax
