Introduction

«Colors have an effect on soul: they can cause feelings, clear up emotions and thoughts which calm us or excite, grieve or please», wrote Goethe. Democritus asserted that there is no color in nature. Newton was the first to explain the nature of color. He understood that for color occurrence the observer is necessary, capable to perceive rays of light and to interpret them as colors. M.V. Lomonosov attached essential significance to the retina («the eye bottom»), considering brain activity as a basis for occurrence of sensations [1].

The basis for all theories of color sight is the well-known physiological facts. Within the retina there are direct organs of vision, visual receptors the reactions in which give rise to neural processes transferred to the optic nerve and higher nervous centers. The sensation of color is caused by electromagnetic radiation with various lengths of waves, from short (dark blue region of spectrum) to long (red region of spectrum). The normal visual system of man is capable to feel adequately radiation in the limits named the visible part of spectrum (about 380-400 nm up to 700-780 nm). The main characteristics of light stimulus are its frequency and intensity. Frequency defines light coloring, and intensity defines brightness. Man, as an energy-information system, receives information from the environment and gives information to the environment. Even ancient people knew that there are natural resonators in human field which are adjusted to certain frequencies of fluctuations. Mechanisms of influence of light of different wavelengths lengths on live objects are different. A French scientist Ferrer and a Romanian scientist Stefenesku-Goanga [2] established that orange, yellow and red colors make breath and pulse become frequent and go deep; the reverse phenomena are caused by blue, dark blue, violet and green colors.

Kotrovskiy A.V., Ustyuzhanina L.V., Efimenko N.N. give advice, practical recommendations for using color in kindergartens, schools.

The problem of color influence on man is considered urgent up to this day. The actual impact of various colors and color light on the person has been studied insufficiently. There is a lot of reference data, but among them there are not enough experimental.

Goal

The objective of the present work was to investigate and define a distinction in reaction to impact of light waves of various lengths depending, on subjects’ temperament by using standard psychological tests, measurement of biophysical parameters, and gas discharge visualization (GDV) technique.

Materials and methods

20 persons, aged from 18 to 22 years, took part in the research. All subjects were recognized as practically healthy according to medical examination. The study was carried out in twilight. The psychotypes were preliminary defined. The research scheme: a) testing by Lüscher color test, GDV measurements, b) taking biophysical parameters in rest (control); c) exposure to light of certain wavelength during 2 minutes; d) taking biophysical parameters, GDV measurements, testing by Lüscher color test after the light exposure. For light influence the subject was exposed to light of red, green, yellow, dark blue color, daylight and absence of light.

For definition of psychological properties of person the Lüscher and Rusalov tests were used. Color-psychological diagnostics (Lüscher test) built on the concept of association of primary colors with certain mood and specific character of relations of person with the environment make it possible to reveal various areas of mental state, composure, efficiency, a tendency to neuroses, character and degree of infringements.

Information possibilities of skin were studied in two ways: registration of potentials in biologically active points (BAP) and use of the GDV bioelectrography technique. For recording BAP biopotentials a multimeter VM – 518, was used (non-polarizing silver-chloride electrodes). Bioelectrography was carried out by means of GDV Camera (St.-Petersburg) [3]. Morphological and physical-chemical changes of the subject in the process living are accompanied by changes of his dielectric characteristics which are the basic agent during the pattern formation of the discharge structure. The structure of kirlian finger glow reveals a wide spectrum of the subject’s psychological, physical and emotional features. Studies of electro-skin resistance of biologically active points gave a chance to reveal its changes depending on changes of the functional state of vegetative nervous system under the influence of electromagnetic radiation with various wavelengths, from short (dark blue spectral region) to long (red spectral region).

Results

By results of definition of psychotypes (Rusalov test), the following groups were defined: 1) sanguine persons – 7; 2) choleric persons – 6; 3) phlegmatic persons – 4; 4) melancholics – 3.

According to the Lüscher color test, the highest changes of values are observed according to workability and deviation from autogenic norm for choleric persons, then sanguine persons, melancholics and phlegmatic persons.

The symmetry coefficient and the glow area increase under the influence: for sanguine persons by dark blue color, for choleric persons and melancholics by green. For phlegmatic persons the symmetry coefficient increases under the influence of green, and the glow area under the influence of yellow color (tab. 1).

Conclusions

Analysis of the parameters with temperament taken into account makes it possible to draw the following conclusions.

1. From all types of temperament the least ones subject to asymmetries are sanguine persons, then choleric persons, phlegmatic persons, and melancholics.

2. According to GDV data, subjects respond to light waves of various length with an increase of GDV parameter values: sanguine persons respond to dark blue, choleric persons to green; phlegmatic persons to yellow color, daylight and absence of light; melancholics to green, red color, and daylight.

The obtained data are intermediate and demand further studies.
