Colorfor.ai

What Colorfor.ai is

Colorfor.ai is a free color workspace for creating palettes, building interface themes, checking contrast, previewing designs, and exporting color tokens. AI Studio interprets a written brief into Safe, Expressive, and Distinctive directions, while a deterministic engine calculates and verifies colors. Its theme builder uses up to three brand colors to generate 40 semantic UI roles and supports light and dark modes. Contrast & Vision checks WCAG 2.2 ratios and offers seven color-vision simulations. Exports include CSS variables, Tailwind, shadcn, SCSS, design tokens, SVG, PNG, and JSON. The service also provides a keyless REST API, an MCP server for AI agents, and embeddable SVG palette badges. Palettes and settings are stored in browser local storage, and uploaded images are processed on-device. AI Studio sends brief text to its provider via OpenRouter only after explicit opt-in; palettes and images are not sent. The free plan covers the tools, API, MCP server, widgets, and exports for personal and commercial use, subject to fair-use limits. The public API has a limit of 120 requests per minute per IP.
