Firstly, understand the color before coloring
When we are coloring, we actually express our subjective emotions. For example, we set a photo to be yellow, and I might want to express a warm feeling. Adjusted to light blue, you may want to express a fresh feeling.
So the color is actually emotional.

Secondly, a variety of color choices
Many times, we may need two or more colors to match each other when we are coloring. Is this time based on subjective feelings? In fact, no, the choice of color is also based on, roughly divided into two types: one is the adjacent color, and the other is the contrast color.
Thirdly, additive color reduction
let's take a look at a few concepts:
The primary color is a "basic color" that cannot be mixed by other colors. In the additive model, there are three primary colors of red, green and blue. The three primary colors are mixed in two, which can form three secondary colors of green, yellow and yellow. After that, you can call up a variety of colors.
In the subtractive model, the three primary colors become green yellow. We can imagine that the picture above is a blank piece of paper. First we draw a circle with yellow paint, then draw a circle with cyan paint, you will see yellow and green mixed.
If we redraw a circle with red pigment, we can see the red color of the yellow mixture and the blue color of the green product. And the green yellows are all mixed together and turned black.

Lastly, adjacent colors and complementary colors
We call two colors adjacent to one color, his adjacent colors. As shown in the figure above, the adjacent colors of cyan are green and blue. The adjacent colors of green are yellow and cyan. The color opposite the color is called his complementary color. For example, the complementary color of red is cyan, and the complementary color of green is color. Adjacent and complementary colors are an important basis for our color grading.
We want to add a color in two ways: one is to increase his adjacent color, and the other is to reduce his complementary color.
