Introduction of several basic methods for color matching of coatings

"Before we learn the method of color matching, we should first understand some common sense of color In nature, the color of objects is ever-changing The reason why people can see the color of objects is that the light of the illuminant shines on the objects, the light radiates on the objects, and the radiation energy of the light acts on the eyes The color of the non luminous object is only presented when it is radiated by the light The color of the object is determined by the reflection and absorption of the light on the object The reason why an object appears green in sunlight is that the object mainly reflects the wavelength of the green range in white light, while the other parts of the spectrum are absorbed by it If you look at the object under the sodium light, you can't see that it is green, because there is no green component in the sodium light that can be reflected by it Here you can see that the visible color of the object follows the light spectrum The ingredients change If an object completely reflects the light, then it looks white to us If it completely absorbs the light cast on it, then it looks black Color is divided into achromatic and colored Achromatic refers to black, white and gray with different shades The achromatic reflectivity on the white black series represents the brightness of the object The higher the reflectivity is, the closer it is to white, and the lower it is, the closer it is to black Color series refers to all kinds of colors except white and black series Different wavelengths of the spectrum are visually represented by hues of various colors, such as red, orange, yellow, green, green, purple, etc To say a certain color clearly, we must consider three basic attributes of color, that is, hue, saturation and lightness, which constitute a unified overall effect in vision Hue refers to the dominant wavelength in the light reflected by an object Different wavelengths produce different color feelings Hue is the basic feature that determines the nature of color Color saturation refers to the brightness of a color Hue, lightness and saturation are the three basic attributes of color, while non color has only the difference of lightness, without hue and saturation The mixed color matching of the coating follows a principle of subtraction The three primary colors are yellow, green and purple, and their complementary colors are blue, red and green The so-called complementary color is that two kinds of color light are mixed to get white color light according to a certain proportion The complementary color of red is cyan, the complementary color of yellow is blue, and the complementary color of green is purple The results of subtractive mixing are 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 indicate that the pigments are added in turn After mixing, the brightness of the color is reduced
Paint color mixing technology mainly includes solid color paint color mixing, transparent paint color mixing and so on Generally, before the color mixing formula is drawn up, it is necessary to analyze according to the color template or the color of a real object First, understand the color range, which color is composed of several colors, which is the main color, which is the secondary color, how the relationship between color and color, and how much each proportion is, and then preliminarily draw up according to experience The color mixing formula shall be debugged by small samples During color mixing, the main color shall be added first, and then the color with strong coloring power shall be added slowly and intermittently and continuously stirred The color change shall be observed at any time, and the principle of "from light to deep" shall be mastered during the whole color mixing process It can be seen from the principle of subtraction that if the sample is compared with the standard plate, the method of subtraction or cyanation can be used for hyper red, the method of subtraction or cyanation can be used for hyper green, and the method of subtraction or yellow can be used for hyper blue, and vice versa, because yellow, green, purple and blue, red and green complement each other, but the mixing of pigments will lead to the decrease of brightness, and the mixed colors can be adjusted by black and white Lightness Before we learn the method of color matching, we should first understand some common sense of color In nature, the color of objects is ever-changing The reason why people can see the color of objects is that the light of the illuminant shines on the objects, the light radiates on the objects, and the radiation energy of the light acts on the eyes The color of the non luminous object is only presented when it is radiated by the light The color of the object is determined by the reflection and absorption of the light on the object The reason why an object appears green in sunlight is that the object mainly reflects the wavelength of the green range in white light, while the other parts of the spectrum are absorbed by it If you look at the object under the sodium light, you can't see that it is green, because there is no green component in the sodium light that can be reflected by it Here you can see that the visible color of the object follows the light spectrum The ingredients change If an object completely reflects the light, then it looks white to us If it completely absorbs the light cast on it, then it looks black Color is divided into achromatic and colored Achromatic refers to black, white and gray with different shades The achromatic reflectivity on the white black series represents the brightness of the object The higher the reflectivity is, the closer it is to white, and the lower it is, the closer it is to black Color series refers to all kinds of colors except white and black series Different wavelengths of the spectrum are visually represented by hues of various colors, such as red, orange, yellow, green, green, purple, etc To say a certain color clearly, we must consider three basic attributes of color, that is, hue, saturation and lightness, which constitute a unified overall effect in vision Hue refers to the dominant wavelength in the reflected light of an object Different wavelengths produce different color feelings Hue is the basic feature that determines the nature of color Color saturation refers to the brightness of a color Hue, lightness and saturation are the three basic attributes of color, while non color has only the difference of lightness, without hue and saturation The mixed color matching of the coating follows a principle of subtraction The three primary colors are yellow, green and purple, and their complementary colors are blue, red and green The so-called complementary color is that two kinds of color light are mixed to get white color light according to a certain proportion The complementary color of red is cyan, the complementary color of yellow is blue, and the complementary color of green is purple The results of subtractive mixing are 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 indicate that the pigments are added in turn After mixing, the brightness of the color is reduced
