1. Hue: the same person, less pro-color, more contrast color. Let the whole feeling be one color. Such as red, blue and purple orange. Red and yellow (fine-tuned when small color blocks, so that the contrast is harmonious), copying the map is a shortcut, absorbing the color from the sample and making a slight change.

2. The purity and brightness should be high, and the overall feeling is bright and bright!

3. Light and shade can be divided into flat color, soft light and shade and hard light and shade, depending on requirements.

4. Edge lines: Some leave edge lines. If there is no edge line left, lock the draft line and color it. . .

I don't know. Just ask ...
