Khroma

Khroma is a specialized AI color palette generation tool for designers, remaining completely free in 2026 with no paid tiers, premium features, or paywalls of any kind. It uses a neural-network algorithm that learns which colors a user likes and blocks the ones they dislike, generating unlimited personalized color combinations with technical specifications including hex codes, RGB values, and accessibility ratings.

Its genuinely free, no-catch business model is unusual and worth highlighting directly: unlike most AI design tools that eventually gate advanced features behind a subscription, Khroma remains entirely free for individuals, students, and organizations of all sizes — the personalization comes from an initial training step where users indicate color preferences, after which the tool generates palettes tailored to that learned taste.

It's aimed at designers wanting unlimited, personalized color palette generation with genuine accessibility data (contrast ratings) built in, with the complete absence of any paywall making it a straightforward, risk-free addition to any design workflow.
