SUMMARY
Photographs can be significantly altered before viewers notice, but three specific colors—skin, sky, and foliage—are treated differently. These 'memory colors' are deeply ingrained in our brains, allowing us to detect even minor deviations from their expected appearance. This sensitivity means that an edit can appear broken if these memory colors are inaccurately rendered, even if other elements of the image are technically perfect. The brain's strict tolerance for these colors means that an incorrect hue in skin, for example, can be perceived as illness, making the photograph fail as a communication tool.
TAKEAWAYS
Skin, sky, and foliage are 'memory colors' with strict perceptual baselines.
Deviations in these memory colors are easily detected by viewers.
An edit's naturalness is often judged by the accuracy of its memory colors.
The brain's tolerance for memory color shifts is low unless justified by lighting.
