What is the paint color mixing mnemonic?

Yellow=white-orchid

Purple=white-green

Cyan=white-red

Yellow+Purple=White-Orchid-Green=Red

Yellow+Cyan=White-Orchid-Red=Green

Purple+Cyan = White-Green-Red=Orange

Yellow+Purple+Cyan = White-Orchid-Green-Red = Orchid

Yellow+Purple + Cyan = white-orchid-green-red = black

Paint mixing and color matching follow a subtractive color principle, its three primary colors are yellow, cyan, purple, their complementary colors are orchid, red, green. The so-called complementary color that is the two color light mixed in a certain proportion to get white color light, red complementary color is cyan, yellow complementary color is blue, green complementary color is purple.

These relational equations mark the relationship between the pigments in order to add, after mixing the resulting color, its brightness is reduced.

Paint toning techniques are mainly solid color paint toning, transparent paint toning, etc. Usually before the formulation of toning formulas, according to the color samples or according to the color of a physical object to be analyzed, the first to understand the range of hue, consisting of several kinds of color, which is the The main color, which is the secondary color, how the relationship between color and color, each accounted for about how much, and then based on experience, the initial formulation of the color formula, and then by a small sample debugging, color mixing, the first to join the main color, and then the coloring power of the color for the vice, slowly and intermittently to join and constantly stirring, to observe the color changes at any time, take a sample wipe, brush, spray or dip in a clean sample, to be the color is stable and the original sample than the color in the whole process of color mixing must master the "color mixing process" and "color mixing process". Color mixing process must master the principle of "from shallow to deep". From the principle of subtractive color method can be seen, if the sample and the standard plate comparison, too red can be used to subtract color or add green, too green can be used to subtract green or add purple, too orchid can be used to subtract orchid or add yellow method of adjustment, and vice versa, because the yellow, green, purple and orchid, red, green complement each other as a complementary color, but the pigment of this mixing will lead to a decline in brightness, you can use the black and white to regulate the mixing of the brightness of the color.
