Eliejesresce K2 Themes

A family of dark Visual Studio Code themes designed around semantic clarity, controlled contrast, and long coding sessions.

The collection contains four distinct interpretations of the same K2 visual language.

Themes

K2 Coherence

Balanced, technical, and restrained. The default expression of the K2 palette.

K2 Vacuum

A deeper and quieter variation built around near-black surfaces and cool accents.

K2 Dim

The expressive member of the family: intense pastel colors over an indigo-plum background.

K2 Endurance

A high-contrast dark theme designed for clear navigation during long development sessions.

Design language

K2 uses semantic color roles rather than assigning arbitrary colors to individual languages:

• Blue represents direction and control.
• Cyan represents structure and types.
• Violet represents transformation and behavior.
• Green represents valid data.
• Amber represents attention and constants.
• Coral represents errors and rupture.
• Neutral tones carry ordinary variables and contextual information.

Each theme reinterprets these roles while preserving a consistent reading model.

Language coverage

The themes include dedicated coverage for:

• Python and Qiskit
• TypeScript and JavaScript
• Java
• Rust
• C
• HTML and Django templates
• CSS
• JSON
• YAML
• Markdown
• Terminal ANSI colors
• Diagnostics, diffs, debugging, testing and notebooks

Architecture

The generated themes are built from:

Primitive palette
        ↓
Semantic roles
        ↓
Shared components
        ↓
Variant overrides
        ↓
VS Code theme files

Raw colors are restricted to the primitive palette. The build validates token references, required surfaces, deterministic output, and contrast contracts.
