In their own words
ColorUI Prompt Palette Studio
ColorUI Prompt Palette Studio turns natural-language design requests into color palettes and explains each color's role. It maps mood, temperature and context to OKLCH properties, arranging colors as primary brand tones, secondary accents and neutral backgrounds. You can give it color names or exact hex codes, lock those choices and generate matching tones around them. Exports include CSS custom properties, W3C design tokens and Tailwind themes, alongside SCSS, JSON, Style Dictionary, Swift UIColor and Android XML. The public API needs no signup or API key, supports CORS and allows 60 requests per minute; it accepts prompt-based generation, harmony rules or random mode, with random counts from 2 to 8. Prompts are evaluated statelessly and are not stored or tied to personal accounts. Palettes may be used personally or commercially without attribution. Integrations include Figma, VS Code, CLI, GitHub, Raycast and MCP. ColorUI also lists image color extraction, an accessibility checker and seven harmony modes. The free plan is available without signup.
Perception
Perception is a web-based design intelligence product for exploring color choices through mood and palette tools. Perception Studio uses generative AI, color psychology and PaletteRank technology to suggest palettes from emotions. Users can request recommendations, add their own colors, inspect a palette’s mood, and copy or download color codes. The Palette Validator assesses existing combinations against perceived moods, while the Palette Dictionary supports searches by term or color. Studio subscribers can access a library of more than 50 million AI-generated palettes. Image color extraction is listed for Lite, Studio and Enterprise, and Adobe tools are the listed export destination. The free Lite plan allows three AI-generated palettes at a time, up to three colors per palette, and analysis of three top related moods. Studio costs $14 / month per member and allows nine generated palettes at a time, up to seven colors, analysis of all related moods, teams of up to 10 users, and unlimited favorites and bookmarks. The homepage says three palettes can be created for free without signing up. Enterprise pricing is by contacting sales.
