TYPES OF HARMONIOUS COLOR COMBINATIONS

1. Using paint colors to create matching color solutions products is determined by the psychological (emotional) and physiological impact on a person of individual colors and color combinations.

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 be a certain relationship between colors (contrast or similarity between colors in terms of hue, lightness or saturation).

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

Color circle

AND- yellow; JO- yellow-orange; O- Orange; KO- red-orange; To- red; P- purple; FP- violet-purple; F- violet; FROM- blue; NW- blue-green; W- green; ZhZ- yellow-green; I, II, III, IV- color zones

4. When choosing color combinations, the characteristics of four psychologically optimal primary colors are taken into account - 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.

6. Contrasting combinations are characterized by the use of colors that have significant differences in hue, saturation and lightness.

Contrasting combinations are the most vivid and active in perception.

To enhance the contrast, the dimensions and surface configuration of the coatings are taken into account. different colors, them mutual arrangement.

6.1. Contrasting colors in hue should be on opposite sides of the color wheel (Fig. 2). When combined, these colors the same values saturation and lightness should reinforce each other's saturation and be perceived as brighter.

6.2. Contrasting colors in lightness should differ significantly with the same color tone and saturation.

6.3. Contrasting colors in saturation should vary significantly with the same color tone and lightness.

7. Related combinations characterized by the use of colors found on color wheel within two basic neighboring colors and shades containing them (Fig. 3). There are four types of related combinations: yellow-red, red-blue, blue-green, green-yellow.

Combination schemes contrasting colors by color tone

Schemes of combinations of related colors

Related combinations are soft, slightly active, static in perception.

8. Related-contrasting combinations are characterized by the use of colors located on the color wheel in neighboring sectors and containing shades of one primary color and two adjacent primary colors (Fig. 4). There are four types of related-contrasting combinations: green-yellow-red, yellow-red-blue, red-blue-green, blue-green-yellow.

Schemes of related-contrasting color combinations

Related-contrasting colors are active, dynamic in perception.

9. Equivalent combinations are characterized by the use of colors of the same color tone with one saturation, but different lightness; with one lightness, but different saturation; with different lightness and saturation.

10. Complex combinations are characterized by the use of chromatic colors with achromatic ones.

Achromatic colors are in good agreement with chromatic colors at different and at equal lightness.

11. Choosing harmonious color combinations for products according to paragraphs. 6 - 10 take into account: the correspondence of colors and their combinations to the functional purpose and operating conditions of the product, volume-spatial structure, tectonics, dimensions and plasticity of the external shape of the product; information content and labor safety requirements; color preferences fashion; color-graphic scheme of the appearance of the product; characteristics of the texture and gloss of enamels of selected colors and the quality of the coating.

2. In terms of decorative properties, the coating must correspond to the functional purpose and operating conditions of the car.

3. The color of the car cabin must be in contrast to the color environment(color of the road, greenery, etc.). The cabin should be light or bright. Reflection of light from the paintwork of the cab (especially the roof) should be high (at least 60%) so that the cab is minimally heated from sun rays.

4. To ensure a favorable working environment for the driver, the color of the cab should not be dark, and the surface should be mirror-gloss. To quickly remove dirt, the texture must be smooth.

5. Volumetric-spatial structure, tectonics, dimensions, plasticity of the external shape of the designed cabin require its one-color coloring with light or bright colors enamels. The color should be clean, unpolluted, bright, expressing the power of the machine, not causing negative emotions and unpleasant associations.

6. To create a variety of colors on the streets of cities, on roads, construction sites, etc., color should be among the colors that complement each other in the system of colors for road transport, construction and road machines.

7. The enamel of the selected color must be mass-produced.

8. The requirements of paragraphs. 2 - 7 correspond, for example, orange (121, 128) and yellow (285, 286) colors. Coverage class III in accordance with Appendix 1.

9. The car is operated in atmospheric conditions of a temperate and tropical climate, is polluted with road dust, dirt and is subjected to periodic washing with hot and cold water using brushes. The turnaround time is 3 years, car maintenance is constant.

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

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

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

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

XV-110 enamel is applied by pneumatic spraying and has a drying mode at a temperature of 18 - 23 ° C for 3 hours or at a temperature of 60 ° C for 1 hour.
