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.
Orange is softer and simpler in comparison to red. It represents happiness, sociability, an extrovert nature as well as joy with the excitement of red and the energy of yellow. It is ideal in overcoming tiredness. It radiates warmth, increases appetite and helps you wake up early in the mornings. Its energy can be lower when saturation is low. It is ideal for use in the rooms of introverted children with problems in socializing. Orange physically represents self confidence, independence and to a certain extent competition. If there is a separate recreation room in your house and your child spends time there with his/her friends you can easily use shades of orange in this room.
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.
Red attracts all the attention and distorts the effect of other colors. The lens of the eye must adjust to be able to focus on red. The natural focal point is behind the retina. The dynamism of red is reduced as it turns into pink with the addition of white and gains softer and calmer undertones. For this reason, the use of red on the walls of children’s rooms must be avoided. Due to its strong and warm effect red could be used as an accent in children’s rooms fashioned in beige, blue and brown. Using intense red in the room of your child who uses it to study, play with his/her friends and sleep in, could have a negative effect on your child. Children could feel themselves tense and aggressive in rooms painted in intense red.
Chromatophores are special pigment-containing cells that may change their size, but more often retain their original size but allow the pigment within them to become redistributed, thus varying the color and pattern of the animal. Chromatophores may respond to hormonal and or neurobal control mechanisms, but direst responses to stimulation by visible light, UV-radiation, temperature, pH-changes, chemicals, etc. have also been documented. The voluntary control of chromatophores is known as metachrosis. For example, cuttlefish and chameleons can rapidly change their appearance, both for camouflage and for signalling, as Aristotle first noted over 2000 years ago
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.
