As with all human beings children are also “psychological and physiological” intellectual beings. Children use their senses to facilitate communication with their environment. They use their sense of sight together with light and colors as well as other visual environmental factors, to communicate. According to research studies, color carries critical importance in the development of the cognitive and motor skills of the children.
Many animals, including mammals, birds, and amphibians, are unable to synthesize most of the pigments that color their fur or feathers, other than the brown or black melanins that give many mammals their earth tones.For example, the bright yellow of an American goldfinch, the startling orange of a juvenile red-spotted newt, the deep red of a cardinal and the pink of a flamingo are all produced by carotenoid pigments synthesized by plants. In the case of the flamingo, the bird eats pink shrimps, which are themselves unable to synthesize carotenoids. The shrimps derive their body color from microscopic red algae, which like most plants are able to create their own pigments, including both carotenoids and (green) chlorophyll. Animals that eat green plants do not become green, however, as chlorophyll does not survive digestion.
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
Some animals such as many moths, mantises and grasshoppers, have a repertory of threatening or startling behaviour, such as suddenly displaying conspicuous eyespots or patches of bright and contrasting colors, so as to scare off or momentarily distract a predator. This gives the prey animal an opportunity to escape. The behaviour is deimatic (startling) rather than aposematic as these insects are palatable to predators, so the warning colors are a bluff, not an honest signal.
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.”
wholly new at the time. It strongly supported Darwin’s theory of sexual selection, arguing that the obvious differences between male and female birds such as the Argus pheasant were selected by the females, pointing out that bright male plumage was found only in species ”which court by day”.The book introduced the concept of frequency-dependent selection, as when edible mimics are less frequent than the distasteful models whose colors and patterns they copy. In the book, Poulton also coined the term aposematism for warning coloration, which he identified in widely differing animal groups including mammals (such as the skunk), bees and wasps, beetles, and butterflies.
