Huemint
Free machine-learning palettes that assign each colour a role in your layout
Overview
Huemint is a free machine-learning colour generator that assigns colours to roles (background, foreground, accents) in a chosen template, trained on about 1.2 million flat-colour designs. It offers transformer, diffusion and random modes, a creativity slider, a pairwise contrast matrix, image upload and a public API for non-commercial use.

Use cases
What you can produce with Huemint
- Colours generated for roles in a chosen layout template
- Transformer, diffusion and random generation modes
- Creativity slider and style presets
- Pairwise contrast matrix for readable combinations
- Recolouring of an uploaded flat-colour design
- Public API for non-commercial use
Huemint understands that a palette only works relative to a layout. Generating colours for named roles, with a contrast matrix to keep text readable, is a better model of the problem than a flat strip, and seeing every result applied to a template speeds up the decision.
It is free, account-free and openly documented, including a public API. The limits are that the API is for non-commercial use only with no uptime promise, there is no company or support behind it, and it does nothing beyond choosing colours.
What we found
Most palette generators give you five unassigned swatches and leave the hard part, deciding which colour goes where, to you. Huemint starts from that hard part. You pick a design template, such as a website, a magazine page, a brand mark, an illustration or a gradient, and it generates colours for specific roles in that layout: background, foreground, accents. Every result is shown applied to the template, which makes it far easier to judge than a strip of chips.
The method is explained on its about page in unusual detail. The developer scraped design thumbnails, kept only those made of flat colour so that photographs and gradients would not pollute the data, and ended up with about 1.2 million images. Generation runs in three modes, transformer, diffusion and plain random, with a creativity slider that sets the sampling temperature: low values give typical, safe combinations and high values give stranger ones. Locking works as expected, and presets such as high contrast, pastel, vibrant, dark and single-hue steer the output.
The most useful control is easy to miss. A contrast matrix lets you set how much contrast each pair of colours should have, on a scale up to 100 for black against white. That is how you ask for readable text on a background; earlier claims that accessibility is handled automatically were not borne out by the site, which leaves those targets to you. You can also upload your own flat-colour design and recolour it.
Huemint is free and needs no account. It also has a public API, documented on the about page, which the developer allows for non-commercial use only and offers as is, with no uptime guarantee. No company, pricing or commercial licence is published. The same independent developer runs Colormind, and a joke companion, Poolors, deliberately samples the colours designers avoid.
For choosing colours that must work together in a real layout, Huemint is among the most thoughtful free tools available. Just treat it as a personal project, not a supported service.
