How do colorful still lifes draw rich color changes?

The so-called environmental color is the influence of the surrounding environment on its own color. For example; A yellow orange and a red apple are put together, so the orange must have the red color of the apple, and vice versa. Moreover, in the case of mutual influence, the colors will blend with each other, just like the example just now, and orange will appear. There are many colors in a group of still lives or landscapes, which interact and blend with each other to produce ever-changing colors. Practice more, think more and observe more, and you will find many beautiful colors. This answer ignores the influence of light, and the color of the light source will cause great changes to the color of the object. However, the default setting for painting is white light. I hope this answer is helpful to you. I wish you the better. The teacher looks at you with new eyes. An ordinary art teacher
