APPENDIX 5 Information
TYPES OF HARMONIOUS COLOR COMBINATIONS

1. The use of paint and varnish coating colors to create appropriate color schemes for products is determined by the psychological (emotional) and physiological impact of individual colors and color combinations on a person.

When choosing color combinations of coatings, their harmony should be the first and main condition.

2. To receive harmonious combinations colors, it is necessary that there is a certain relationship between the colors (contrast or similarity between colors in color tone, light or saturation).

3. The relationship between colors is achieved using the principles of choosing color combinations along the color wheel (Fig. 1).

Color circle

F - yellow; ZhO - yellow-orange; O - orange; KO - red-orange; K - red; P - purple; FP - violet-purple; F - purple; C - blue; SZ - blue-green; Z - green; ZhZ - yellow-green; I, II, Ш, IV - color zones

Crap. 1

4. When choosing color combinations, take into account the characteristics of the four psychological optimal primary colors - yellow (221), red (7), blue (427), green (324) and intermediate ones - orange, violet-purple, yellow-green.

5. Color combinations are divided into five main groups according to psychophysiological characteristics: contrasting, related, related-contrasting, equitonal, complex.

9. The car is operated in atmospheric conditions temperate and tropical climates, becomes contaminated with road dust, dirt and is subject to periodic washing with hot and cold water using brushes. The time between repairs is 3 years, the car is constantly maintained.

10. The specified operating conditions are satisfied by paint and varnish coatings obtained on the basis of melamine-alkyd enamel ML-12 and perchlorovinyl enamel XB-110.

The coating system, consisting of two layers of ML-12 enamel applied to a primed surface, is stable in atmospheric conditions of temperate and tropical climates for 3 years.

The coating system, consisting of two layers of XB-110 enamel applied to a phosphated and primed surface, is also stable in temperate and tropical climates for 3 years.

11. In terms of color, texture, gloss and class of enamel ML-12 and XB-110 meet the requirements: the color of enamel ML-12 is orange (121, 128), the color of enamel XB-110 is yellow (285, 286), coatings according to the recommended - smooth , glossy (ML-12), semi-gloss (XB-110), the maximum achieved coating class is II for ML-12 enamel and III for XB-110 enamel.

12. Taking into account the level of production of the painting area (production - serial, painting on continuous conveyors using pneumatic spraying or spraying in electric field, drying in thermoradiation drying chambers at a temperature of 130 ºС), you should choose ML-12 enamel, which is applied by the specified method and has a thermoradiation drying mode at a temperature of 130 ºС for 20 minutes.
