Score: 4.7/10 (Innovation: 5, Technical: 4, Documentation: 5, Utility: 5)

Color Studio is a web-based palette builder that uses the OKLCH color space to generate sequential, diverging, and categorical color palettes for data visualization and UI design. It offers anchor-based color matching, tonal scales, and accessibility previews, making it easier to create cohesive color systems than with HSL-based tools.

Target audience: frontend developers, data visualization engineers, UI/UX designers
