What is the difference between oil painting and watercolor painting?

Different materials, different painting methods and different expressive force.

Watercolor is a painting method of mixing transparent pigments with water, which is called watercolor for short. Because the color is transparent, one layer of color can cover another layer, which can produce special effects. But too much mixing or covering will make the color dirty and the water will dry quickly. Therefore, watercolor painting is not suitable for large-scale works, but suitable for fresh and lively small paintings such as landscapes. The color is easy to carry and can also be used as a sketch collection material. Compared with other paintings, watercolor painting pays great attention to expression. Its painting methods are usually divided into "dry painting" and "wet painting".

Oil painting (an oil painting; ; A painting in oils is a kind of painting made on canvas linen, cardboard or wood by mixing pigments and quick-drying vegetable oils (flax oil, poppy oil, walnut oil, etc.). ). Diluents used in paint are volatile turpentine and dry linseed oil. The pigment attached to the picture has strong hardness and can keep luster for a long time after the picture is dried. With the hiding power and transparency of the pigment, the painted object is vividly displayed, with rich colors and strong three-dimensional sense. Oil painting is one of the main types of western painting.

Extended data:

The predecessor of oil painting is1egg painting in European painting before the 5th century, which was developed by the Dutch painter Jan Van Eyck after improving the painting materials (1385-144 1). Later generations praised Yang Van Eyck as "the father of oil painting" because he made a unique contribution to the in-depth development of oil painting techniques. Modern oil paintings mostly use linseed oil to blend pigments and paint on processed cloth or wood boards. Because oil painting pigments do not change color after drying, many colors will not become dirty after mixing, and painters can draw rich and realistic colors. Oil painting pigments are opaque and have strong coverage, so the painting can be covered layer by layer from deep to shallow, giving the painting a three-dimensional effect.

Watercolor painting itself has two basic characteristics: first, most of the pictures have a transparent visual experience; The second is the fluidity of water in the process of painting. Therefore, watercolor painting is different from other paintings in appearance and creative techniques. The transparency of pigment makes watercolor painting produce the surface effect of Amin car, while the fluidity of water will produce a dripping, natural and free and easy taste.
