Basic knowledge of paint palette

     We paint palette in the learning method, first color should be aware of some common sense. Natural colors of objects in the ever-changing, people are able to see objects in color, is due to the light emitter in the object, light radiation in the objects, the role of light in the eyes of radiation energy by the results. Not the color of light-emitting objects only when shot by the light was shown by the color of objects by light reflected in the objects and decided to absorb the situation. An object in sunlight green is the result of this object will mainly white in the green range of wavelengths reflected, while the spectra of other parts of it were absorbed, if observed in the sodium lamp light on the object can not see is the green, sodium light because the light is not green light it could be an element of reflection, here we can see that the objects in the visible light spectrum color is with the composition and change. If an object is shot entirely reflective of light, then the objects we seem to be white, and if it is completely absorbed in its projection of light above it, the object appears to be black.

     Color is divided into non-color and color, non-color is the black, white and between the two different shades of gray, white-black series of non-color objects on behalf of the reflectivity of lightness. The higher the reflectivity, the nearly white, the more low, close to black. Color Series is the white-black series in addition to a variety of colors outside. Spectrum of different wavelengths in visual performance for a variety of color tones, such as red, orange, yellow, green, blue, purple and so on. To be sure of a clear color, must take into account the color of the three basic attributes, namely, hue, saturation and brightness, these three in the formation of a unified vision of the total. Color is the light reflected from objects with which to determine the dominant wavelength, and different wavelengths produce different color perception, color is to determine the nature of the basic characteristics of color. Color saturation is an obvious degree of color. Hue, brightness and color saturation are the three basic attributes, non-color only lightness difference, but not hue, and saturation of these two attributes.

     Paints, pigments, dyes and other mixed-color follow the principle of a mixed Hypochromic law, the three primary colors are yellow, blue, purple, their complementary color is blue, red, green. The so-called premium色即two light received by a certain percentage of mixed white light, red is the complementary color cyan, yellow complementary color is blue, green complementary color is purple. Hypochromic law mixed results summarized as follows:

    Yellow = white - blue

 Purple = white - green

 Cyan = white - red

 Yellow + purple = white - blue - green = red

 Yellow + cyan = white - blue - red = green

 Purple + cyan = white - green - red = blue

 Yellow + purple + cyan = white - blue - green - red = black

     These relations are marked with paint-style followed by the sum of the relationship derived from a mixture of colors, its brightness is reduced.

     The main technology paint color palette is Paints, transparent color, metallic color, etc., usually in the preparation of color formulations ago, according to the color model or color of a particular kind of analysis, first of all understand the scope of Hue from several color composition, which is the main color, which is the vice-color, color and how the relationship between color, about half the proportion of the number, and then drawn up based on experience to find the initial color formula, and then by sample testing, Tiu color, the first to join the main color, and then the color shading stronger as deputy, slowly adding intermittent and continuous mixing, it is necessary to observe the color change at any time, sample clean, brush, spray or dip in the clean model, the question color stable than the original model for color, color in the whole process must have the "easy-to-digest" principle. Hypochromic law from the principle can be seen, if the sample compared with the standard plate, had red Hypochromic method can be used or blue, too green can be used by green or purple, blue-off can be used by Huang Lan or methods to adjust , and vice versa, because of yellow, blue, purple and blue, red, green mutually complementary color, but this kind of mixed paint will lead to decline in brightness can be used to black and white to regulate the blending of lightness.

     At present, paint manufacturers have generally black, white, red, green, blue, yellow, blue, purple and other color or color masterbatch for conducting real paint palette, the use of light-colored, light-colored domain in white base plus less than 5% of the high concentration of color palette, dark varnish reinforcement domain using quantitative methods of color palette. And transparent color palette is selected, some transparent pigment or dye slurry liquid, transparent color change also affected by the thickness of the coating and the substrate effects of the actual color palette should be the required thickness and at the end of comparable material. Metallic paint palette in addition to follow the basic principles of mixing, we must also take into account the self-luminous type of metal paint on the impact of color, relatively complicated. Paint palette, and they knew the basic knowledge, hard work and more training, will soon have this technology.
