Venture Codex Theme

Open the codex. Light the lantern. The adventure starts on line 1.

Venture Codex is a vivid VS Code theme built for developers who spend more hours inside the editor than outside it. Every keyword, every function, every glyph is colored like a page from an illuminated manuscript: distinct, readable, made to be lived in. Whether you're chasing a bug at 2 a.m. or shipping a feature on a Monday morning, your eyes should not have to fight your code.

Four coordinated variants share the same color identity:

• Venture Codex Dark — primary variant, vivid hexadic accents on a deep green-cyan ground.
• Venture Codex Light — warm background, vivid dark accents tuned for daylight.
• Venture Codex High Contrast Dark — WCAG-AAA-friendly, for accessibility and projector use.
• Venture Codex High Contrast Light — WCAG-AAA-friendly, warm background with vivid dark accents.

Contributing

Contributions are welcome. To propose changes:

1. Check WCAG contrast for any new or changed colors against the relevant background.
2. Open a pull request with a clear description and, if applicable, screenshots.

When proposing color changes:

• Prefer adjusting existing palette values over introducing new colors.
• Preserve the role separation across variants (Dark, Light, HC Dark, HC Light) so the four themes feel like one family.
• Keep this README and CHANGELOG.md updated with any user-facing change.
