Khroma

Khroma is a browser-based color tool that trains a small algorithm on a designer's personal taste instead of generating palettes from fixed rules. Users start by picking a set of favorite colors, and Khroma uses that selection, combined with patterns learned from thousands of popular human-made palettes, to generate an effectively unlimited stream of combinations that match the style they've indicated. Beyond generation, the tool includes a search function that filters results by hue, tint, value, specific colors, hex codes, or RGB values, so a designer looking for something close to a particular shade can narrow results quickly rather than scrolling through random output. Palettes can be viewed in several formats, including typography samples, gradients, flat palette swatches, or overlaid on a custom uploaded image, which helps evaluate how a combination will actually look in context. Each result comes with color names, hex and RGB values, ready-to-use CSS, and WCAG accessibility ratings for contrast compliance. Khroma is built for designers and other creative professionals who want color choices tailored to their own preferences rather than generic starter palettes. It was created by George Hastings. The site doesn't state a price, and it isn't clear from the available information whether there's a paid tier beyond the free browser tool.
