Khroma
Khroma is a free AI color tool that learns your color preferences and generates personalized palettes with accessibility ratings and CSS export.
About
Khroma trains a personal neural network on the colors you select from a curated set, then uses that model to generate color combinations you are likely to like while filtering out tones you tend to avoid. Results can be browsed as typography samples, gradient pairs, full palettes, or overlaid on custom images, making it practical to evaluate how a combination works in context rather than as abstract swatches. Every palette comes with hex codes, RGB values, CSS snippets, and WCAG accessibility ratings for contrast. You can save favorites to a personal collection and search across generated results by hue, tint, value, or specific hex code. Khroma is completely free with no paid tiers.
