10015.io AI Color Palette Generator vs ColorUI Prompt Palette Studio

10015.io AI Color Palette Generator creates customized color palettes from user prompts using AI. The maker describes it as a free online tool for designers and developers. Users choose a light or dark theme before generating a palette. Each result has primary, accent, background, and text colors, with two additional shades for each of those four colors. A basic design preview shows the generated colors together. Users can export palettes as CSS variables or as hexadecimal color codes in free text; CSS variable export is described as a way to incorporate colors into website designs. The tool runs on the web, and its listed plan costs nothing. It does not extract colors from images. The tool was designed and coded by Fatih Telis, a frontend developer based in Istanbul, Turkey. The site's privacy policy says it collects log data such as IP address, browser version, pages visited, and visit times, and says absolute security cannot be guaranteed. Users can contact the maker by email about issues, feedback, or tool suggestions.

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.
