Warning coloration is effectively the ”opposite” of camouflage, and a special case of advertising. Its function is to make the animal, for example a wasp or a coral snake, highly conspicuous to potential predators, so that it is noticed, remembered, and then avoided. As Peter Forbes observes, ”Human warning signs employ the same colours – red, yellow, black, and white – that nature uses to advertise dangerous creatures.”[28] Warning colors work by being associated by potential predators with something that makes the warning colored animal unpleasant or dangerous.

When cephalopod molluscs like squid and cuttlefish find themselves against a light background, they contract many of their chromatography, concentrating the pigment into a smaller area, resulting in a pattern of tiny, dense, but widely spaced dots, appearing light. When they enter a darker environment, they allow their chromatography to expand, creating a pattern of larger dark spots, and making their bodies appear dark. Amphibians such as frogs have three kinds of star-shaped chromatophore cells in separate layers of their skin. The top layer contains ’phosphorescent’ with orange, red, or yellow pigments; the middle layer contains ’sophomores’ with a silvery light-reflecting pigment; while the bottom layer contains ’melanophores’ with dark melanin.

The yellow in green lends an elegant character to this color while the blue renders it warm. Light green reduces pressure. Symbolically green represents the power of nature and life and as such it is considered to be the most natural, relaxing, calming and balanced color. Red signals “stop” there is danger, while green signals “safe crossing” and thus reduces the tension in the body. Green can be used with ease in nurseries, and in children’s and teenagers’ rooms. The use of color green in nurseries will ensure a peaceful and comfortable transition into sleep for the baby. When green is used with more undertones of yellow, it clarifies the mind, and therefore can be used in teenagers’ rooms to foster success in school. The serenity of blue and the mental clarity achieved with yellow will have a good impact on them.

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).

Müllerian mimicry was first described by pioneering naturalist Fritz Muller. When a distasteful animal comes to resemble a more common distasteful animal, natural selection favors individuals that even very slightly better resemble the target. For example, many species of stinging wasp and bee are similarly colored black and yellow. Muller’s explanation of the mechanism for this was one of the first uses of mathematics in biology. He argued that a predator, such as a young bird, must attack at least one insect, say a wasp, to learn that the black and yellow colors mean a stinging insect. If bees were differently colored, the young bird would have to attack one of them also. But when bees and wasps resemble each other, the young bird need only attack one from the whole group to learn to avoid all of them. So, fewer bees are attacked if they mimic wasps; the same applies to wasps that mimic bees. The result is mutual resemblance for mutual protection.
