What it does

Colormind generates colour palettes with a machine learning model, for example to suggest colours for a website or illustration. POST a JSON request to colormind.io/api/ and get five RGB colours back; you can fix some colours and let the model fill in the rest. Models change daily, the service is briefly down at the daily reload, and it uses http only. Free for personal and non-commercial use, no key needed; commercial use by arrangement.
