Some animals are colored purely incidentally because their blood contains pigments. For example, amphibians like the olm that live in caves may be largely colorless as color has no function in that environment, but they show some red because of the haem pigment in their red blood cells, needed to carry oxygen. They also have a little orange colored riboflavin in their skin. Human albinos and people with fair skin have a similar color for the same reason.
Much to our disbelief, a study published in the Art Therapy: Journal of the American Art Therapy Association 22(2) pp. 81-85 provides support that coloring mandalas or geometric patterns actually does help lower stress and anxiety levels. Nancy A. Curry, BA, completed this project while pursuing an undergraduate degree at Knox College with then associate professor, Tim Kasser, Ph.D., who is now the Professor and Chair of Psychology at Knox College.
Protective resemblance is used by prey to avoid predation. It includes special protective resemblance, now called mimesis, where the whole animal looks like some other object, for example when a caterpillar resembles a twig or a bird dropping. In general protective resemblance, now called crypsis, the animal’s texture blends with the background, for example when a moth’s color and pattern blend in with tree bark.
Medical Daily shared an article in which “Dr. Stan Rodski, a neuropsychologist who also has his own line of adult coloring books, says that coloring elicits a relaxing mindset, similar to what you would achieve through meditation.” The neuropsychologist further mentions that “like meditation, coloring allows us to switch off our brains from other thoughts and focus on the moment. Tasks with predictable results, such as coloring or knitting, can often be calming.”
Henry Walter Bates’s 1863 book The Naturalist on the River Amazons describes his extensive studies of the insects in the Amazon basin, and especially the butterflies. He discovered that apparently similar butterflies often belonged to different families, with a harmless species mimicking a poisonous or bitter-tasting species to reduce its chance of being attacked by a predator, in the process now called after him, Bayesian mimicry.
Hugh Bamford Cott’s 500-page book Adaptive Coloration in Animals, published in wartime 1940, systematically described the principles of camouflage and mimicry. The book contains hundreds of examples, over a hundred photographs and Cott’s own accurate and artistic drawings, and 27 pages of references. Cott focussed especially on ”maximum disruptive contrast”, the kind of patterning used in military camouflage such as disruptive pattern material. Indeed, Cott describes such applications
