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.
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.
Aggressive resemblance is used by predators or parasites. In special aggressive resemblance, the animal looks like something else, luring the prey or host to approach, for example when a flower mantis resembles a particular kind of flower, such as an orchid. In general aggressive resemblance, the predator or parasite blends in with the background, for example when a leopard is hard to see in long grass.
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.
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.”
In addition to affecting our mood, emotions and actions, color also affects the ambiance of a space as well as how big or small, coldly or warmly it is perceived. Colors are the most commonly used tool by children to express their emotions and thoughts. Although the preferences of children show a general commonality based on age group, their color choices can differ based on their moods, the way they express themselves and their feelings.
