Pigments are colored chemicals (such as melanin) in animal tissues. For example, the Arctic fox has a white coat in winter (containing little pigment), and a brown coat in summer (containing more pigment), an example of seasonal camouflage (a polyphenism). 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.
The main mechanisms to create the resemblances described by Poulton – whether in nature or in military applications – are crypts, blending into the background so as to become hard to see (this covers both special and general resemblance); disruptive patterning, using color and pattern to break up the animal’s outline, which relates mainly to general resemblance; mime sis, resembling other objects of no special interest to the observer, which relates to special resemblance; counter shading, using graded color to create the illusion of flatness, which relates mainly to general resemblance; and counter illumination, producing light to match the background, notably in some species of squid.
Purple stimulates the part of the brain related to creativity. At the same time it has a calming effect. Violet is a lighter shade of purple and is included in the spectrum. Purple on the other hand is a complex color and in terms of color type there are big differences between them. Girls like pink and purple very much. Purple is a color appropriate for children. Purple can be easily used in the rooms of preschool children that are usually involved in creative activities as well as teenage girls’ rooms for purposes of contributing to their academic skills. Due to the fact that it also contributes to physical and spiritual serenity, purple and its different shades can be used in the rooms of hyperactive and highly animated children.
Winston Churchill once said “We shape our buildings, thereafter they shape us”. (Grangaard, 1993) Environmental factors play an essential role in the nutrition, growth, development and education of children. Each and every characteristic of their physical environment contributes to their education and development. Although residential location, design, order, plan, colors as well as the areas of play may contribute to a child’s learning, these same factors may also hinder the revelation of their potential.
Their interest was in examining coloring therapy which “combines elements of art therapy and meditation” (pp. 81). In the study, 84 undergraduate students received “a brief anxiety-induction,” and were randomly assigned to color either a mandala, plaid form, or blank piece of paper (pp. 81). Curry and Kasser reported, “that anxiety levels declined approximately the same for the mandala- and plaid-coloring groups and that both of these groups experienced more reduction in anxiety than did the unstructured-coloring group”
While many animals are unable to synthesize carotene pigments to create red and yellow surfaces, the green and blue colors of bird feathers and insect carapaces are usually not produced by pigments at all, but by structural coloration. Structural coloration means the production of color by microscopically-structured surfaces fine enough to interfere with visible light, sometimes in combination with pigments: for example, peacock tail feathers are pigmented brown, but their structure makes them appear blue, turquoise and green. Structural coloration can produce the most brilliant colors, often iridescent. For example, the blue green gloss on the plumage of birds such as ducks, and the purple blue green red colors of many beetles and butterflies are created by structural coloration. Animals use several methods to produce structural color, as described in the table.
