In contrast to black, it is considered reliable and supportive by many people. It can be specifically used in teenagers’ rooms. Due to the fact that it is a down-to-earth color influenced by the energy of red and yellow and the seriousness of black, it could prove helpful in developing feelings of responsibility and protection in teenagers. It is a color associated with will and possession. Brown as a color has positive influence on the family and friendships of teenagers. At the same time it gives peace and serenity. It calms teenagers high spirits and helps them to remain down to earth in the academic field. To achieve success in education simultaneously with relaxation you can choose to color a part of your teenager’s room in a shade that is yellow intense. Moreover, silky beige and straw colors can be used together in nurseries. This color gives rise to feelings of confidence and is relaxing.
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.
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.
As the ovules develop into seeds, the ovary begins to ripen and the ovary wall, the pericarp, may become fleshy (as in berries or drupes), or form a hard outer covering (as in nuts). In some multi seeded fruits, the extent to which the flesh develops is proportional to the number of fertilized ovules. The pericarp is often differentiated into two or three distinct layers called the exocarp (outer layer, also called epicarp), mesocarp (middle layer), and endocarp (inner layer). In some fruits, especially simple fruits derived from an inferior ovary, other parts of the flower (such as the floral tube, including the petals, sepals, and stamens), fuse with the ovary and ripen with it. In other cases, the sepals, petals and/or stamens and style of the flower fall off. When such other floral parts are a significant part of the fruit, it is called an accessory fruit. Since other parts of the flower may contribute to the structure of the fruit, it is important to study flower structure to understand how a particular fruit forms.
Sight starts developing after the 6th month in babies and development continues until the age of 10. Sight is one of the most important senses that connects us to the world. Light and color have a mesmerizing effect on us. On average, the human eye can perceive 150 different colors in visible light. This means a person with normal sight can differentiate between millions of different colors. Color is one of the most important characteristics that can help us assess, estimate and define an object. Each and every person has certain reactions stored in their perceptions and as such the perception of each color addresses the related emotion.
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
