A color picker is a graphical user interface that allows users to select colors using input fields, sliders, and preview swatches. This tool goes beyond basics by enabling:
- Dynamic HEX ↔ RGB synchronization
- Alpha channel transparency control
- Interactive EyeDropper to grab colors from anywhere on screen
🎨 Palette Generator
Using chroma.js, the generator creates a smooth transition between white → selected color → black using the perceptual LAB color space. You control the number of stops (from 3 to 12), allowing you to explore:
- Tints (lighter variations)
- Base tones
- Shades (darker variations)
