A powerful REST API to handle all kind of colors.

What Color is also a REST API by itself: you can access every existing page by changing the suffix into another type, for example html into json.

Currently supported formats are:

Format What it is for Try it
html Provides all information formatted as HTML for the browsers. www.whatcolor.is/rgb/220+20+60.html
ico Creates a favicon in the requested color with a size of 48 × 48 px. www.whatcolor.is/rgb/220+20+60.ico
idml The response is an Adobe® InDesign Markup Language file (IDML), that can be opened in Adobe® InDesign. The colour is then already been stored in the colour palette. www.whatcolor.is/rgb/220+20+60.idml
jpg This generates a response in the format of a JPEG image that can be integrated into a website, for example. www.whatcolor.is/rgb/220+20+60.jpg
json Returns the requested color information in a JSON-formatted way. This is especially useful if you want to access color information with another digital service. www.whatcolor.is/rgb/220+20+60.json
png This generates a response in the format of a PNG image that can be integrated into a website, for example. www.whatcolor.is/rgb/220+20+60.png
