Pigments are colored chemicals (such as melanin) in animal tissues.
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.
Mimicry means that one species of animal resembles another species closely enough to deceive predators. To evolve, the mimicked species must have warning coloration, because appearing to be bitter-tasting or dangerous gives natural selection something to work on. Once a species has a slight, chance, resemblance to a warning colored species, natural selection can drive its colors and patterns towards more perfect mimicry. There are numerous possible mechanisms, of which by far the best known are:
Fruits are the means by which angiosperms disseminate seeds. Edible fruits, in particular, have propagated with the movements of humans and animals in a symbiotic relationship as a means for seed dispersal and nutrition; in fact, humans and many animals have become dependent on fruits as a source of food. Accordingly, fruits account for a substantial fraction of the world’s agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings.
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.
