The Color API
Your fast, modern, swiss army knife for color. Pass in any valid color and get conversion into any other format, the name of the color, placeholder images and a multitude of schemes. There are only two endpoints you need to worry about, /id and /scheme, and you can read the docs about both. Each endpoint is available in JSON[P], HTML & SVG format. The SVG format can be saved or used as an img[src] attribute for super-easy embedding/sharing!

The Color API — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is The Color API free to use?
The Color API is listed in our free catalogue, but it requires some form of authentication, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does The Color API need an API key?
The Color API requires some form of authentication. Check the provider's documentation for which scheme it expects.
Can I call The Color API from browser JavaScript?
Yes. The Color API returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Is The Color API still working?
Yes, as of 2026-09-18. Our automated check reached The Color API and recorded a 100% reliability score with a median response time of 1252 ms. We re-check on a schedule, and this page updates with the result.
Is The Color API available over HTTPS?
Yes. The Color API serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
