Abyssal

A deep, low-noise dark theme designed for developers who spend hours in their editor.

Abyssal uses layered dark surfaces, restrained borders, and semantic syntax colors to keep your code readable without visual noise.

Your editor should disappear while your code stays visible.

Philosophy

Abyssal is built around one idea:

Your editor should disappear while your code stays visible.

Most dark themes try to make the editor visually exciting.

Abyssal takes the opposite approach.

The interface stays quiet. Syntax gets a clear hierarchy. Important states receive focused accents. Nothing should compete with the code you're working on.

Design principles

• Deep layered surfaces
• Low visual noise
• Strong syntax hierarchy
• Focus-driven cyan accents
• Subtle borders
• Comfortable contrast
• Git-aware colors
• Terminal-aware palette
• Long-session readability
• Consistent cross-language highlighting

Color System

Abyssal uses a restrained semantic color system.

Role	Color
Editor	#070B14
Primary text	#F1F5F9
Focus	#67E8F9
Functions	#C4B5FD
Types	#67E8F9
Classes	#A5B4FC
Strings	#86EFAC
Numbers	#FDE68A
Constants	#F0ABFC
Errors	#FB7185

The goal isn't to use as many colors as possible.

The goal is to give each important semantic category a recognizable visual role.

Recommended Settings

Abyssal works well with the default VS Code experience.

For the intended visual experience, we recommend:

• Semantic highlighting enabled
• Standard VS Code font rendering
• Default editor antialiasing
• Minimap enabled or disabled according to preference

Abyssal does not require a specific programming font.

Use the font you are most comfortable coding with.

• JavaScript
• TSX / React
• Python
• Go
• Rust
• Java

• Deep editor background
• Clear primary text
• Focused selection states
• Distinct bracket matching
• Comfortable inactive text
• Low-noise whitespace and punctuation

Syntax

• Semantic syntax hierarchy
• Distinct functions
• Clear types and classes

Git

Git decorations use dedicated colors for common repository states, including:

Errors, warnings, information, and hints use dedicated semantic colors so problems are visible without overwhelming the editor.

Contributing

Contributions are welcome.

If you find a syntax highlighting issue, contrast problem, or inconsistent UI state, please open an issue with:

• The language or VS Code component
• A screenshot when possible
• The current Abyssal version
• Your VS Code version
• A description of the expected behavior

For larger changes, please open an issue before submitting a pull request so the design direction can be discussed first.

---

Feedback

Abyssal is designed for developers who spend long hours inside their editor.

If something feels distracting, difficult to read, too bright, or visually inconsistent, that feedback is valuable.

The goal is simple:

Less noise.

More focus.

Better coding.
