How to color in painting

1 First, read the theory of color composition carefully, lay a solid theoretical foundation of color composition, and then take some typical demonstrations as exercises to master the basic skills of color matching.

2. Be careful in color matching. Generally, the samples are tried first, and the amount of tinting paint is obtained initially, and then the details are prepared according to the results of the samples. First, adjust the secondary color and secondary color in a small container.

3. First add the main color (the color with large dosage and low tinting power), then slowly and intermittently add the dark color (or tinting) with high tinting power, constantly stir and observe the color change at any time.

4, "from shallow to deep", especially when adding pigments with strong coloring power, don't overdo it.

5. When matching colors, the colors of paint and dry film will be slightly different. The colors of various paints are generally light when wet, and dark when dry. Therefore, if the sample is a dry sample, the color matching paint needs to be dried before it can be compared. If the sample is wet, you can drop a drop of the sample in the color-matching paint to see if the two colors are the same.

Color matching technology:

1. First, use the color picker tool to place four points in the highlights, midtones and dark parts of a person's face, and check the proportional components of cyan, magenta, yellow and medium gray in the colors respectively, so as to determine the color composition and distribution ratio of the original photo.

2. Then according to a global color composition standard of human skin proposed by Americans as a reference, or choose a skin color I like as standard data, check whether the original photo has color cast and the specific data of color cast (color cast here refers to the comparison with the specific data of the reference photo).

3, rely on color scale and curve tools, correctly input reference standard data, and use tools such as color balance, hue/saturation, and optional colors for fine adjustment. ?

4. The issue of transparency has a lot to do with the pre-shooting of photos. Of course, a considerable part of the opaque problem can be solved later, but the process is more complicated, mainly depending on the correct use of channels.
