Color Lab
Jun 13, 2026 · via hackernews.com
Interactive 3D color space explorer that generates perceptually uniform palettes for design systems.
Perceptually uniform color ramps are hard to create manually. This bridges color science and practical output, useful for design system tokens and accessible data viz palettes.
Color Lab is a browser-based tool that lets you explore color spaces in 3D — think slicing through gamuts, not just picking swatches — while also generating perceptually uniform color ramps and cohesive palettes. The core value is that it operates in perceptual color spaces (likely OKLCH or similar) rather than the RGB/HSL fudging most designers default to, which means the output actually behaves consistently across lightness levels. It's trying to be both a learning environment and a practical asset generator in one.
