Khroma

Khroma uses your color choices to train a browser-based algorithm that generates palettes based on colors you like and blocks colors you don’t. It draws on thousands of popular palettes and displays combinations as typography, gradients, palettes, or custom images.

Designers can search and filter by hue, tint, value, color, hex, or RGB values, then save combinations to a personal collection. Each pair includes color names, hex codes, RGB values, CSS code, and a WCAG accessibility rating.
