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.
Abbott Handerson Thayer’s 1909 book Concealing-Coloration in the Animal Kingdom, completed by his son Gerald H. Thayer, argued correctly for the widespread use of crypts among animals, and in particular described and explained countershading for the first time. However, the Thayers spoilt their case by arguing that camouflage was the sole purpose of animal coloration, which led them to claim that even the brilliant pink plumage of the flamingo or the roseate spoonbill was cryptic—against the momentarily pink sky at dawn or dusk. As a result, the book was mocked by critics including Theodore Roosevelt as having ”pushed [the ”doctrine” of concealing coloration] to such a fantastic extreme and to include such wild absurdities as to call for the application of common sense thereto.
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.
Batesian mimicry was first described by pioneering naturalist Henry W. Bates. When an edible prey animal comes to resemble, even slightly, a distasteful animal, natural selection favors those individuals that even very slightly better resemble the distasteful species. This is because even a small degree of protection reduces prediction and increases the chance that an individual mimic will survive and reproduce. For example, many species of hover fly are colored black and yellow like bees, and are in consequence avoided by birds (and people).
their upper sides seem to me to consist of a multitude of thin plated bodies, which are exceeding thin, and lie very close together, and thereby, like mother of Pearl shells, do not only reflect a very brisk light, but tinge that light in a most curious manner; and by means of various positions, in respect of the light, they reflect back now one colour, and then another, and those most vividly. Now, that these colours are only fantastical ones, that is, such as arise immediately from the refractions of the light, I found by this, that water wetting these colour, which seemed to proceed from the alteration of the reflection and refraction.
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.
