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.
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.
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.
Aggregate fruits form from single flowers that have multiple carpels which are not joined together, i.e. each pistil contains one carpel. Each pistil forms a fruitlet, and collectively the fruitlets are called an etaerio. Four types of aggregate fruits include etaerios of achenes, follicles, drupelets, and berries. Ranunculaceae species, including Clematis and Ranunculus have an etaerio of achenes, Calotropis has an etaerio of follicles, and Rubus species like raspberry, have an etaerio of drupelets. Annona have an etaerio of berries.
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.
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”
