This is a production-grade single-page web application for picking and converting colors in the OKLCH and LCH color spaces. It provides interactive 2D charts (WebGL2-accelerated), sliders, numeric inputs, and a 3D gamut model (three.js) to explore and select colors. The app supports sRGB, Display P3, and Rec.2020 gamuts, and can parse and output a wide variety of color formats (hex, rgb, hsl, oklch, lch, lab, linear RGB, Figma P3 hex, etc.). State management is handled by nanostores with persistent settings in localStorage, and the URL hash is used for shareable color states. The codebase is well-structured with clear separation between core color logic (lib/), reactive stores (stores/), and UI components (view/). It includes a comprehensive test suite and CI/CD pipelines for deployment to Firebase Hosting. The architecture is a monolith frontend with no backend, built with Vite, TypeScript, PostCSS, and Pug templates.
Retroma is a CSS theme for the Obsidian note-taking application, designed to evoke a retro aesthetic inspired by arcade machines, vintage software, and early web design. The theme uses an algorithmic color system based on the modern CSS `oklch()` color space to dynamically generate palettes from a single accent color, ensuring perceptual uniformity across light and dark modes. It offers extensive customization through the Style Manager plugin, including per-note font and accent overrides, a collection of 79 styled callouts, and multiple preset configurations. The repository contains the theme manifest, preset JSON files, and example callout documentation, but the core `theme.css` file was not provided for analysis, limiting the ability to assess code quality and reusability. Based on the README and manifest, the theme appears well-designed and actively maintained, with a focus on accessibility and visual personality.
