Colorfor.ai vs Perception

Colorfor.ai is a color workspace for making palettes, building interface themes, checking contrast, previewing designs, and exporting color tokens. Its AI Studio turns a written brief into Safe, Expressive, and Distinctive directions; a deterministic engine computes and verifies the colors. The theme builder creates 40 semantic UI roles from up to three brand colors, with light and dark modes. Contrast & Vision checks WCAG 2.2 ratios and includes seven color-vision simulations. Export formats include CSS variables, Tailwind, shadcn, SCSS, design tokens, SVG, PNG, and JSON. The service also offers a keyless REST API, an MCP server for AI agents, and embeddable SVG palette badges. Palettes and settings stay in browser local storage, while image uploads are processed on-device. AI Studio sends brief text to its provider through OpenRouter only after explicit opt-in; palettes and images are not sent. Site Recolour sends a submitted public page address for rendering, and its screenshots are cached for about 24 hours. The free plan covers tools, API, MCP server, widgets, and exports, subject to fair-use limits. The public API allows 120 requests per minute per IP.

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.
