Coding Independent Code Points (CICP) is a colorspace labeling technology, originally deployed for video but now also used for still images or animated images. It is standardized in ITU H.273.

CICP is already used in AVIF and JPEG XL images. PNG Third Edition also added CICP support. The current state of CICP in PNG is described in the PNG implementation report and, for browsers, can be summarized like this:
