ColorChecker™ images set to 5000 K of three select colors with variations of illuminant CCT. Standard acquisition settings and uncorrected white balance were used to photograph three colors from a micro ColorChecker under six distinct illuminants. Using an iPhone 11, the same exposure was made with different devices showing how panel A (light skin), panel B (blue sky), and panel C (orange–yellow) appear differently under each source. By setting the color balance to 5000 K, we demonstrate how far off the colors might look, uncorrected, to a camera. Matching the CCT to the illuminant (color correction) would allow for a more accurate rendition, akin to human visual systems.
