Color Relationship in Oil Painting

Modeling and color, this is the basic language used to express oil painting. The so-called oil painting is actually a combination of graphic art and color art. How to understand and express color, in oil painting occupies an important position.

First, the so-called color relationship of oil painting color relationship, here mainly refers to the object in different light under the general law of its color changes. For a long time, human beings have been more intuitive to understand the color of the object, when people's minds only the concept of intrinsic color, that is, the so-called red sun, yellow land, white clouds, blue sky? Only the development of modern natural science to provide us with new knowledge about the color, from then on mankind finally understand the reason why nature presents colorful, purple and red, is due to a variety of different objects to absorb or reflect light waves of the ability to different reasons. Then realized that in addition to the object's own inherent color, the color of the object presents an important role in the color of the light source and the environment color. Humans discovered the relationship between warm and cold colors very early, that is, all the red and yellow colors are warm, while all the blue and green colors are cold. Warm colors usually create a kind of exuberant stimulation, while cold colors leave a sense of withdrawal. Flexible use of the contrast between warm and cool colors allows us to create a strong sense of space on the screen. Warm and cool in painting is again a relative concept, either cold or warm depending on the contrast. An experienced colorist will be able to quickly and appropriately grasp the subtle changes in color tones in a picture, and take the initiative to boldly use this relationship to serve their own artistic creation. For a beginner, learning how to master and have this ability is a very important subject. Because the objective object of the color tone of the warm and cold changes, often are not that sharp, they are often in a fuzzy state, only when we master the color knowledge, it is possible to go to the correct understanding and judgment. We will be any one of the primary colors and the other two primary colors mixed with the composition of the inter-color can be obtained by adding the complete color of daylight, so we can recognize the color of the three groups complement each other (i.e., complementary color relationship).

Red? Green (blue ten yellow)

Blue? Orange (yellow ten red)

Yellow? Violet (red + blue)

Primary colors are the purest. Color, and as long as we add the contrasting color component it will immediately appear turbid up, and the more the original color state to maintain the color contrast is stronger, add the contrasting color (inter-color) the more components, the weaker the contrast of colors. It can be said that the ability to skillfully master the color of the warm and cold contrast and complementary color relations, is whether we can learn a good color is an extremely important key, there is no shortcut on this issue, only after a long period of hard training, it is possible to master and comfortable with the use of this language of color performance.

Second, the oil painting hue hue is the color tendency, that is, the color of the last name, in fact, even the most ambiguous variety of gray has its own clear color tendency. The direction of identification is still the same as the previous introduction, as long as we put a variety of different gray together to compare, will immediately determine which color is reddish-gray, which color is greenish-gray, or yellowish-gray, purple-gray? A painting that lacks a clear color tendency is boring, and a master of color painting is very good at trying to find some subtle tendency in that very close hue. This must be a big problem for beginners, and their paintings are generally monotonous, dark and dull. In the era of classical oil painting, since the painters at that time depended more on the sketch relationship of the picture, the oil paintings at that time were basically ? Sauce color? , rarely showing much of a clear color palette. Today's modern oil painting makes all this fundamentally changed, many modern painters can be said to be painted with pure color, which is why when we visit the modern oil painting exhibition often can always feel a kind of fresh air and the passion of life.

Third, the oil painting chromaticity chromaticity refers to the degree of darkness and depth of color, also known as brightness. If you use the untrained eye to properly distinguish the color chroma is very difficult. For example, if we squeeze red pigment and green pigment directly from a tin tube, the average person will probably think that the red color is brighter than the green color because it is more stimulating to the human eye. But if we take a black-and-white photo of it, you may find that their shades are the same. Distinguish between different shades of color and chromaticity is very close to the depth of the color block, also need to use the method of comparison. If we can not distinguish the subtle chromatic relationship between the color blocks on the screen, then the work certainly does not show a rich sketch level.

Fourth, oil painting purity (saturation) purity refers to the degree of color purity. The concept of purity is also closely linked to the hue, in general, the more clear the hue of the color the higher the purity of the color (except for white or certain colors with powder). Primary colors are the purest colors and therefore have the highest saturation. On the contrary, the more often the color is blended or the more powder or black is added, the less saturated it is. A colorful painting should always have at least one or a few large or small pieces of saturated color. No saturated color picture is definitely weak; Conversely, once the saturation exceeds the needs of the picture, it will make people feel that the color is shallow and monotonous. At this point we have to try to reduce it, the method is also mixed into a variety of contrasting colors, grays and pigments with powder.
