Colorfor.ai
What it is
Colorfor.ai is a color workspace for creating palettes, building UI themes, checking contrast, previewing designs and exporting color tokens. Its AI Studio takes a written brief and proposes Safe, Expressive and Distinctive directions; a deterministic engine computes and verifies the colors. The theme builder turns up to three brand colors into 40 semantic UI roles and supports light and dark modes. Contrast & Vision checks WCAG 2.2 ratios and offers seven color-vision simulations. Users can export 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 stay in browser local storage, while uploaded images are processed on-device. AI Studio sends brief text to its provider via OpenRouter only with explicit opt-in. The free plan includes the tools, API, MCP server, widgets and exports, subject to fair-use limits.
