Color Mixed Laminated Fabric Information

Mixing two colors or several colors with each other is called color mixing. It has three mixing methods: the three primary colors of color light, namely red, green, and blue, are mixed to become white light, which is called additive color mixing. The three primary colors of pigments, red (magenta), yellow (lemon yellow), and blue (lagoon), become black when mixed, which is called subtractive color mixing. There is also a neutral mix, the spatial mix. (1) Additive color mixing Additive color mixing is the mixing of colored lights. As the amount of mixing of different colors of light increases, the brightness of the color gradually increases. When full-color light is mixed, it appears white, that is, white can be obtained by adding the three primary colors of light. Add red and green to get yellow, add green and blue to get cyan, and add blue and red to get magenta. This is the first intercoloration of the color light. If the three primary colors of the colored light are added to the three adjacent secondary colors, the second secondary color of the colored light can be obtained. By analogy, the color of the approximate spectrum can be obtained. Therefore, the colors red, green, and blue are the most ideal colors for additive color mixing. The additive color mixing effect is completed by the human visual organ, so it is a kind of visual mixing. The result of additive color mixing is changes in hue and brightness. The purity remains unchanged. If the three primary colors of colored light are mixed in different proportions, more colored lights can be obtained. For example, red light and green light can be mixed in different proportions to obtain: orange, yellow, and yellow-green light. Red light and blue light can be mixed in different proportions to obtain: magenta, red-violet, and purple-red light. Blue light can be mixed in different proportions to obtain: green-blue, cyan, turquoise and other colors of light. (2) Subtractive color mixing: The mixing of various pigments or various dyes should be mixed by subtractive color mixing. The demonstration of object color is due to the object’s selective absorption and reflection of light in the spectrum. “Absorb” means to subtract. When the light source remains unchanged, when two or more pigments are mixed, it is equivalent to white light minus the absorbed light of each pigment, and the remaining reflected color light becomes the color of the mixed pigment. The mixed new pigment increases its ability to absorb colored light, while its reflective ability decreases. Therefore, after the pigment is mixed, the brightness and purity of the color are reduced, and the color also changes. The more types of pigments are mixed, the more absorbed light is subtracted from the white light, and the corresponding reflected light is less. In the end, the color is similar to gray.

According to the mixing principle of subtractive color method, magenta, yellow and cyan are different All colors can be obtained by mixing them in proportion, so these three colors are the three primary colors of the pigment (i.e., the first color); two different pigments in the three primary colors are mixed with each other, and the resulting three colors are called the three secondary colors (also known as the second color). Secondary colors); by mixing the three secondary colors with the three adjacent primary colors, the tertiary color (i.e. the complex color) can be obtained. (3) Neutral Mixing Neutral mixed colors are also called space mixing. It has similarities with the mixing of colored light. It is also the color mixing effect formed during the process of retinal information transmission when colored light enters the human eye. Neutral mixing is additive color mixing, which is not a luminophore itself, but a mixture of reflected light. For example, several colors are painted on a disk, and the various colors are mixed by the rapid rotation of the disk. The reflected light of this mixed color quickly stimulates the human eye one after another or simultaneously, thereby obtaining the mixed color in vision. Or by intersecting and juxtaposing points or lines of different colors, within a certain visual distance, it can also produce a color mixing effect similar to that caused by the rotation of a disk. The spatial mixing has the following rules: (1) If colors that are complementary to each other are mixed in a certain proportion in space, achromatic gray and chromatic gray can be obtained. For example, when red and green are mixed, gray, red gray, and green gray can be obtained. (2) Color space mixing of non-complementary color relationships produces an intermediate package of two colors. For example, if you mix red and green, you can get red-violet, purple, and cyan-violet. (3) Mixing the color space of the color system with the color space of the five-color system also produces the intermediate color of the two colors. Different purity of red and gray. Mixing red and white can produce light reds of different brightnesses. (4) The brightness of the new color produced when color spaces are mixed is equivalent to the intermediate brightness of the mixed color. (5) There are conditions for color juxtaposition to produce spatial mixing. The mixed colors should be fine dots, thin lines, and dense at the same time. The smaller the dots and the thinner the lines, the more obvious the blending effect will be. The effect of spatial mixing produced by the juxtaposition of colors is related to the visual distance, and the mixture must be produced outside a certain visual distance. The further the distance, the more obvious the mixing effect. (4) Complementary colors In physics, two colors that add to white light and two colors that mix to form black or gray-black are called a pair of complementary colors. Two complementary colors are at opposite ends of the diameter of the hue circle. For example, the addition of red light and cyan light produces white light, and the addition of green light and magenta light also produces white light. The addition of magenta and green in the pigment produces black, and the addition of yellow and violet also produces black. The corresponding colors of visual residual images are also complementary colors. The relationship between complementary colors is a person’s psychological balance towards colors and is also an important basis for visual physiology.
