AIColors vs Colorfor.ai

AIColors is a web-based color palette generator and set of color tools. Describe a mood, theme, or style to generate a harmonious palette of five colors, then copy a single hex code or the whole palette. The tools directory also includes color contrast checking, conversion, harmony and gradient generation, image color extraction, and palette visualization. Its contrast checker compares pairs against WCAG 2.2 and APCA, with live previews, OKLCH-based suggestions, and color blindness simulation. The converter provides copy-ready snippets for CSS, Tailwind, Swift, Android, and Flutter. Image extraction uses k-means clustering in OKLab, and images stay in the browser. The privacy policy says palette prompts, color values, uploaded images, and generated palettes are not stored by an AIColors account system, and most color work runs locally in the browser. The generator is available in nine languages. There is no public API for the homepage generator. AIColors is free, with no account required for unlimited palette generation. Users are responsible for reviewing outputs in their product, legal, brand, and accessibility context.

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.
