The Color

About The Color

The Color API is a web service for color conversion, identification, and scheme generation. It accepts a color value in hex, RGB, CMYK, HSL, or HSV format and returns that color transposed into all of these formats, along with a matched name from a dataset of over 2000 named colors, a demonstration image URL, and a best-contrast color for text overlay. Responses are available in JSON, JSONP, HTML, and SVG.

The API also generates color schemes seeded from a supplied color, with selectable modes including monochrome, monochrome-dark, monochrome-light, analogic, complement, analogic-complement, triad, and quad. Scheme length can be specified within limits, and each generated scheme includes a full color object for every constituent color.

The service exposes two main endpoints, /id and /scheme, and is aimed at developers needing programmatic color identification, format conversion, or scheme generation, such as for placeholder images or UI theming. It is open source.
