Khroma

About

Khroma takes a different approach to color selection. Instead of browsing through random palettes hoping something clicks, you train the AI on your preferences first. Pick 50 colors you like from a curated set, and Khroma's neural network learns your taste. From that point on, every palette it generates is biased toward combinations you'll find appealing — while still introducing complementary colors you might not have considered. The training step takes about 3 minutes and the results are immediately noticeable. If you gravitate toward muted earth tones, Khroma won't waste your time with neon gradients. If you prefer high-contrast combinations, it won't suggest pastel-on-pastel pairings. The AI has been trained on thousands of the most popular human-made palettes across the internet, so it understands which color relationships work in practice, not just in theory. The generator shows colors in four practical views: typography (text on background), gradient (smooth transitions between colors), palette (multi-color combinations), and custom image (your colors applied to a photo). This is more useful than a grid of hex codes because you can immediately see how colors perform in real design contexts. The typography view alone saves time that would otherwise go to creating test compositions in Figma. Every color combination includes detailed information: name, hex code, RGB values, CSS code, and WCAG accessibility rating for text-background pairs. The accessibility rating is particularly valuable — you can filter results to only show combinations that meet WCAG AA or AAA contrast standards, which is a requirement for most professional web projects. Search and filter capabilities let you narrow results by hue, tint, value, or specific hex and RGB values. You can build an unlimited library of saved combinations for future reference. The best part: Khroma is completely free. No hidden costs, no premium tiers, no paywalls, no credit limits. Everything the tool offers is available at zero cost, which makes it one of the few genuinely useful AI design tools that doesn't eventually ask for your credit card. The limitation is narrow scope. Khroma generates color palettes — that's it. No design generation, no layout suggestions, no brand kit management. It's a single-purpose tool that does its job exceptionally well, and the price (free) makes it an automatic addition to any designer's toolkit.
