Oil painting originated in Europe and was invented by the Dutch in the 0/5th century. It uses linseed oil to mix pigments and paints on treated cloth or wood boards. Because the oil painting pigment does not change color after drying, and it will not get dirty after mixing many colors, artists 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. Oil painting is suitable for creating large-scale and epic masterpieces. It has become the main way of painting in the history of western painting, and the existing western painting is mainly oil painting. Most murals are also made with oil paints and creative methods. /kloc-In the late 20th century, due to the development of science and technology, many new materials were applied in the field of oil painting, such as acrylic pigments and coatings.
