ColorMagic vs iWantHue

ColorMagic is a free web tool that generates color palettes with AI, and it also offers an API. Palette inputs can be names, images, text, or hex codes; users can upload an image to extract colors. Results can be copied as colors, CSS, or gradient effects, or downloaded as PNG. Saving favorite palettes requires login. The site also includes a random color generator, color mixer, contrast checker, color name finder, coloring book, and color shades. Its mixer combines two colors at an adjustable ratio and reports the result in hex and RGB. The free API offers a GET endpoint to search palettes by query, including tags and text, but the API may be changed or removed without warning. The site says palette generation is unlimited and may show ads. The coloring book supports online coloring and downloading or printing artwork; pages are free for personal use, classrooms, and therapy sessions without an account. For the coloring book photo feature, processing happens in the browser unless a user chooses to upload through Illustrate with AI. The privacy policy says the service uses Google Analytics cookies and may collect profile and submitted information, device details, access history, referrers, IP addresses, server logs, and identifiers.

iWantHue generates and refines color palettes for data scientists working with data visualization. Users can set hue, chroma, and lightness constraints, then sort colors by difference, hue, chroma, lightness, or randomly. Its calculations use CIE Lab, with HCL controls, and palette distribution uses either k-means clustering or force-vector repulsion. An option helps improve palettes for colorblind users. The web interface exports HEX, RGB, HCL, and LAB JSON, CSS color lists, and JavaScript settings. Developers can install the JavaScript package with npm for Node.js or browser use; its generator accepts a seed to reproduce a palette from a data attribute. The npm module also includes precomputed palettes from 2 to 15 colors, including colorblind alternatives. Very large palettes may include similar colors when the selected color space is constrained, though the first colors are arranged for the greatest possible distinction. The Fancy preset is limited to generic palettes of up to 10 colors. iWantHue is free.
