ColorUI Prompt Palette Studio vs HanoDecor Color Palette Generator

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.

HanoDecor Color Palette Generator is a web tool that uses AI to create palettes from uploaded photos, hex codes, or a described mood. It can extract dominant colors from images of rooms, nature, or artwork, then produce palettes of 3–12 colors. Users can choose complementary, analogous, triadic, split-complementary, or tetradic harmony rules and fine-tune individual swatches. AI room previews show palettes on room photos. Exports include hex codes, RGB values, CSS variables, and shareable images. The tool also checks WCAG contrast compliance across color pairings. HanoDecor identifies homeowners, interior designers, real estate professionals, and brand and web designers as intended users. The tool page describes the generator as free to use and says no download is needed. It advertises a seven-day free trial, while the pricing page lists a three-day trial for Starter and seven days for Pro. Starter costs $19 a month billed yearly ($228/year); Pro costs $29 a month billed yearly ($348/year). HanoDecor says uploaded photos are not shared, sold, or used to train AI models without explicit consent.
