The facial skin color of a character is not a single intrinsic color, but it is generally divided into five different shades of light and dark due to the difference in light exposure. The highlight color is located in the high-profile and high-profile part of the face and should be close to the light source color. The intrinsic color is located in the face of the high-key to the midtone portion, generally presents the skin itself is the most normal color; the middle color is in the middle of the facial junction of light and dark, generally showing a little dark. Intrinsic skin color; shadow color is located in the entire dark side, most affected by the ambient diffuse reflection light, generally showing a dark red biased towards cool hues; reflective color is located in the shadow, affected by the reflection of nearby objects, generally showing a dark red tea tone . The changes in the shades of the above five tones are the basic rules for color to express the facial three-dimensionality.

The color of each part of the face has different intrinsic colors, and the color proportions of the three color plates should be mastered. The matching rule is:

The highlight color is the skin color plus the light source color. Due to the influence of different light, the highlight color is very rich, with pale flesh, pink, light yellow, lavender with a green barley, etc., some close to achromatic. The nose is the center of the face. Because it is an arc-shaped body that protrudes from the face, it is most susceptible to light color. The highlight of the bridge of the nose and nose is the spirit of the face. It must be bright and bright. The yellow version of the highlights is required, and the red version is slightly softer to enable the high light to come out. High-light dot values ​​are determined according to the color change. The cold tone highlights are slightly darker than the yellow and magenta versions, and the gray tone is calibrated based on the gray balance. The highlights of the warm colors and the fine spots on the cyan plates should be determined according to the appropriate conditions of the paper used and the size of the highlight areas. High-quality coated paper, high light color is also very important, should put fine, high light color appears moist and beautiful. If the condition of the paper is poor and the area of ​​the highlight is small, then put less or not, so as to avoid dark light.

The forehead is a part of the face that protrudes and has a large area, and receives light brightly. Less frontal muscles, slightly yellowish flesh, and slightly darker yellow version. On the dark side, the reddish flesh of the bright side should be gradient to a yellowish warm gray, but it can only be displayed slightly in the contrast. The gradient is slightly transparent and cannot be over-emphasized.

The cheek is the largest part of the facial area, and the structure is complex, full of muscles and capillaries, so the color is full of ruddy. However, people with different genders and different characteristics on the cheeks differ greatly. The cheeks of girls and children are ruddy, smooth and delicate. The elderly must be old and the cheeks should not be red. Yellow and magenta version of the proportion of the configuration is: 20% of young children, then 40% of magenta; 30% of the average male magenta is 35%; magenta is generally greater than about 10% of yellow.

The facial part of the forehead and the forehead is the same as the flesh-colored system, but it is colder than other skin-colored parts, because it shrinks more than the forehead and twitches. The upper and lower forehead is the natural color of the skin color, which is also the natural part of the skin color. The combined ratio of yellow and magenta versions is basically the same, except that the cyan version is slightly more than the forehead and cheeks.

The lip is the thickest part of the facial muscles and is also an important part of expressing emotions. The black version may not be added or added. The green version must be used properly. It must be processed with a thick red and a solid, with a sense of three-dimensionality. The edges should be slightly imaginary, and they cannot be rigid or rigid. The upper lip is slightly deeper, the sides are deeper in the middle, the lower lip is more reflective, and the yellow version is lighter than the magenta version. Women and children should be ruddy, and men's lips are thicker and less reflective. Lip color is rich in color change, and the depth of color depends on the age and sex of the person, and is used for different color processing. Teeth are white and yellow, yellow can not be too much.

3. Character photography light treatment

The originals of the portraits of people are all devoted to the use of light, and the beauty of light is to be handled when making plates. The first thing to distinguish is whether the direction of the chief ray is positive, side, or backlit. We must also clarify three faces of the person's face: the light-receiving surface, the medium-toned surface, and the dark surface. The brightness of the midtone surface cannot exceed or lie flat on the light receiving surface; the brightness of the dark surface cannot exceed or level the surface of the hand. If the dark relationship of the face is inverted or flattened, even if the skin color is treated well, it gives a sense of discomfort, so the bright color of the face cannot be simply emphasized and the relationship between the face and the shade of the figure is lost. The following points should be mastered during copying:

1 Pay attention to the light effect of the overall picture, and have a strong sense of light. The version must be ambiguous and the contrast must be opened. The color level of the light-receiving surface cannot be flat, and dark tone must be deep;

2 The highlights should be bright, and the highlights should be concentrated. The high light part of the picture has the strongest light sensitivity, the area with high light and bright light is smaller, and the smaller the area is, the more concentrated the light is, and the high light can shine out. The extremely high light that does not pass through the net must be abundant, and the shallow mid-tonal level must be enriched in order to express the brightness of the high light;

3 To highlight the chief ray. Some manuscripts are confused by light and can't distinguish between frontal light and back light. It is necessary to make local corrections on the manuscript, consciously focus the chief rays on the central key part of the picture, and compress the four sides of astigmatism so as to concentrate the sight, highlight the theme, and enhance the artistic effect;

4 deal with reflection. Note that the intersection of the face of a person's face on the dark side to the reflective surface is obvious, and some reflections require artistic processing.
