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.
Advertising coloration can signal the services an animal offers to other animals. These may be of the same species, as in sexual selection, or of different species, as in cleaning symbiosis. Signals, which often combine color and movement, may be understood by many different species; for example, the cleaning stations of the banded coral shrimp Stenopus hispidus are visited by different species of fish, and even by reptiles such as hawksbill sea turtles.
Warning coloration can succeed either through inborn behaviour (instinct) on the part of potential predators, or through a learned avoidance. Either can lead to various forms of mimicry. Experiments show that avoidance is learned in birds, mammals, lizards, and amphibians, but that some birds such as great tits have inborn avoidance of certain colors and patterns such as black and yellow stripes.
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.
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
Many common terms for seeds and fruit do not correspond to the botanical classifications. In culinary terminology, a fruit is usually any sweet-tasting plant part, especially a botanical fruit; a nut is any hard, oily, and shelled plant product; and a vegetable is any savory or less sweet plant product. However, in botany, a fruit is the ripened ovary or carpel that contains seeds, a nut is a type of fruit and not a seed, and a seed is a ripened ovule.
