Lumen Themes
A minimal, clean, and high-tech VSCode theme featuring a monochromatic Dark variant (Noir) and a "Warm Paper" Light variant (Blanc).
Design Philosophy
Lumen is built on the principle of Functional Hierarchy. Instead of overwhelming the editor with a full color palette, Lumen uses color and brightness strategically to guide your focus.
- Noir (Dark): A strictly monochromatic experience with an International Orange accent reserved for logical flow (functions, control flow, tags).
- Blanc (Light): A soft, warm paper aesthetic using muted colors that prioritize legibility and long-form coding comfort.
