ColorUI Prompt Palette Studio vs PaletteMaker

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.

PaletteMaker is a web app for creating AI-generated color palettes and previewing them in design examples. Users can filter palettes by color tone and number of colors, with each palette containing two to five colors. Colors can be randomized, changed individually or removed. Preview contexts include web and mobile UI, branding and logos, illustration, typography, posters and patterns. Exports are available for Procreate, Adobe ASE, image and code formats. The app is offered free, with all current features free forever and no stated usage limits; there is no separate free trial. PaletteMaker began in 2022 as a pet project by Tanya K, a senior visual designer from Europe based in Riga, Latvia. It is intended for designers and non-designers, including creative professionals and color lovers. The site offers English, German, French, Portuguese and Japanese options, and provides LinkedIn and email contact links. The Free plan is free.
