Problem
Simple pickers solve HEX/RGB, but real workflows mix contrast, palettes, and formats. An earlier prototype already explored this; it needed a modern base and UX that matched daily use.
Approach
I rebuilt the idea in Next.js + Styled Components: interactive picker, conversions (RGB, HEX, HSL…), palette generation, and contrast checks. Each color tweak updates the rest of the panel immediately.
Outcome
Color utilities usable day to day, open-sourced on GitHub.
Role
Product and full-stack frontend implementation — from migrating the legacy picker to the color-manipulation experience.
