How to apply black and white paint?

(1) The application of white oil paint: (1) White, as the color with the highest lightness and the strongest covering power, is often used to brighten a local color. (2) Mixing white with any other color will improve the brightness of this color and reduce its purity. (3) Equal mixing with black can produce pure gray, unequal mixing will get different lightness of gray. Mixing white is not the only way to make the color lighter. In nature, any color changes with the intensity of light. Such as red, when it is dark it tends to be blue-purple, when it is bright it tends to be orange. In other words, to enhance the bright red color, you must add orange yellow. (2) The application of black oil paint: Black and any other color harmony may become "dirty" color. (2) Black as an exclusive color, generally applied to the screen independently, or mixed with white into gray use. (3) There are three traditional methods to reconcile black: Deep red + ripe brown + half emerald green = warm black Cooked brown + plain blue + half emerald green = cold black Ripe brown + emerald + deep red = neutral black (3) White and black usage of modern oil painting: Classical oil painting uses white pigments, in addition to color, mainly to strengthen the contrast between light and shade, so that the pigments become opaque and thick in the bright part, the purpose is to use white to brighten the color. Modern oil painting, especially impressionist painters, after observing the outdoor light, generally added white to the pigment to lighten the overall color of the picture. Impressionist painters such as Manet, Monet and Seurat mixed the colors used with lead and white in different degrees to increase the brightness of the colors and achieve the effect of natural light. Black was not found in the spectrum, so the impressionists eliminated it from their palette. Then they learned to blend "black". Combine the pure tones of ultramarine, magenta and emerald green to make them close to black. Renoir called black "the queen of colors", lautrec, Cezanne, Gauguin, Matisse, Picasso and other modern outstanding oil painters have used black in their paintings, which makes their painting colors full of deep power.
