How to draw a gouache still life? I am a beginner. Every time the background color is spread, the card is stuck, the color matching control is not good, and the picture always looks dirty. Also, besides red. For your reference, the following picture was written and copied by me before. The background can be a little gray Kaplan, which will give you a breathable feeling. When using colors, you must be pure, and don't add many colors together. The color must be brighter than what you see, because the paint will be black and gray when it dries.
