Darwin explained such male-female differences in his theory of sexual selection in his book The Descent of Man. Once the females begin to select males according to any particular characteristic, such as a long tail or a colored crest, that characteristic is emphasized more and more in the males. Eventually all the males will have the characteristics that the females are sexually selecting for, as only those males can reproduce. This mechanism is powerful enough to create features that are strongly disadvantageous to the males in other ways. For example, some male birds of paradise have wing or tail streamers that are so long that they impede flight, while their brilliant colors may make the males more vulnerable to predators. In the extreme, sexual selection may drive species to extinction, as has been argued for the enormous horns of the male Irish elk, which may have made it difficult for mature males to move and feed.
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.
Countershading was first described by the American artist Abbott Handerson Thayer, a pioneer in the theory of animal coloration. Thayer observed that whereas a painter takes a flat canvas and uses colored paint to create the illusion of solidity by painting in shadows, animals such as deer are often darkest on their backs, becoming lighter towards the belly, creating (as zoologist Hugh Cott observed) the illusion of flatness, and against a matching background, of invisibility. Thayer’s observation ”Animals are painted by Nature, darkest on those parts which tend to be most lighted by the sky’s light, and vice versa” is called Thayer’s Law.
Depending on the situation they are used in, colors can give rise to positive or negative effects. Each color used by itself in a room with the expectation of creating a positive effect, carries the possibility of causing a negative reaction instead. Being subject to excessive stimuli can cause changes in breathing pattern, pulse, blood pressure and muscle tension. On the other hand, too little stimuli can lead to anxiousness, sleeplessness, excessive emotional reaction, loss of concentration and nervousness.
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”
