reactions to light and color 

numerous scholars have under different experimental methods to the biological effect of light on the diverse forms of life were examined. first and foremost visual effects have been studied, but also other forms of perception, to understand how light and color without passing through the eye effect. it became clear that all organisms on individual basis by the light tightened. the experiments with plants and animals can be interesting to draw conclusions on similar reactions in humans.
plants are known to stretch the opposite of light, which is called phototropism. mechanically explained this phenomenon by the fact that the supporting cells of the plant and the tendency, on the dark side to grow faster. the light is bluish shadow and thus seem to support the rapid development, while growth is reddish light. it has been found that seed potatoes which are stored red light, no air germs form. later, these potato plants then a good harvest.
john ott, the long time nature shots filmed for walt disney, made the experience that spotlights the artificial rhythm of flowering plants durcheinanderbringt completely, ie not open buds, and fruits ripen at the wrong time. gradually, he discovered the profound connection between light, color, and the fertility of the plants.
many of his observations are today for the modern, highly efficient greenhouse crops is essential. flowers and vegetables can be industrially almost any season produced. it only depends on the artificial light dose so that colors and light-dark cycles on the best. each plant are tailored. the results are remarkable, but many of these fast-growing, man-controlled plants, if they are in a natural environment.
edible plants, in various experiments in color-bred, reacted with great vehemence on the respective farbschwingungen. they showed an altered appearance, had a different flavor and a different consistency. cress was reddish light thin and bitter, with a green light strohig. under blue light sprouted lush, tasty plant, while the control group with normal white light prospered.
the wine has been discovered that yeasts feel most comfortable and the best wine, when the mash tubs are illuminated yellow. another experience is that fat in a blue and ultraviolet light will quickly turn rancid. to avoid this, milk is often offered in red-brown glass bottles.
light and special color will also affect the life cycle of most animals. even bacilli are turning to the light. it has been many animal experiments carried out to determine the different reaction patterns to better understand. unfortunately, many of the lessons learned so unrestrained in the farming and animal husbandry exploited.
a hen lays down, for example, one egg per day. you can however manipulate the animal by two cycles of twelve light suspends. the poor hen now believes that in these two days twenty-four hours had passed and rushed to the twice the number of eggs to lay, to continue with the artificial sun to keep pace. when subjecting the hen with fluorescent, ultraviolet light can be found in other fresh eggs immediately foul differ. fresh eggs show a pink tinge, while old look bluish.
in the pelzzucht are also light and colors used to obtain higher profits. the mink bears a white winter coat for natural camouflage, and for those white ermine the dealer gets a better price than the normal brown fur. in nature, the animal reacts to the extremely short winter days with a hormone distributions to its fur, the white color. a farmed mink, however, every day for several hours a bluish light, which for the frigid polar day is typical. regardless of minus temperatures and snowfall will be the beast suggests that winter just around the corner and that the time had come to change the fur. if, however, chinchillas during the time of their mating and pregnancy of a blue light to be suspended, you get a surplus of
females, with a softer and finer fur, which they are commercially valuable makes. during an irradiation with red light would artificially incidentally a surplus of male animals produce. similar manipulations are possible in the fish.
the starlings and pigeons around london's piccadilly circus - another example - are always the huge, colorful flickering neon suspended. the intense fluorescent lighting stimulates their sex hormones and therefore makes them the whole year fruitful. normal starlings lay only may to august of eggs, which is also the natural rhythm of life of other species is.
the most extreme examples of the influence of colors produced in animal mice and rats. the animals were in special glass and caged for months continuously exposed to a certain color light. despite the best of feed, plenty of air and died after discharge and after many animals in the unilateral "farbnahrung». above all, red, orange and pink were deadly in their one-sidedness. it could be this monotonous farbeinflüsse with the consequences of a long compare vitamin deficiency. mice, only with red and pink light were developed in the course of the experiments an increased appetite and increased weight quickly, but they died because of the duration of irradiation. ever appear red and yellow light, the hunger feelings in mammals to stimulate, while blue and green light rather dampening effect.
color but also healing effects on plants and animals. in veterinary medicine, for example, has successfully überanstrengte work horses in stables with blue glass windows to ensure the recovery phase to intensify. the stable of race horses got a blue or a red interior orange paint. the animals in the blue division calmed after a race relatively quickly, whereas in the orange-red barn housed horses stayed longer nervous.
as we already know, most mammals with the exception of higher primates is limited perceive colors. for this reason, this color effect on a person other than the visual way have unfolded. the horses do not receive the color of their eyes, and it also has another factor in this experiment out of the farbforscher and art professor johannes itten reported. in the blaugestrichenen shed, there were no flies, but the horses were in the orange-red barn plagued by them.
the fact is that yellow dress on a summer evening, all sorts of insects and attracts mosquitoes. previously you could see it as a bad omen, and yellow was therefore a reputation for being a bad color to be. furthermore, beelzebub in arabic: 'lord of the flies ". here we see an intertwining of biological facts with superstition, primitive religion and magic, their traces in the next chapter we want to go after, because colors we have, of course, people always heavily influenced. we are, however, today one of the first generation of people who have an extremely high farbdosis
is exposed - by neon signs, disco lights, films and screens. we should, therefore, from time to time on the results of the animal mind a sense of responsibility to developed how much color in our lives can intervene.
