How to draw the contrast between cold and warm, and the priority of reality and reality in gouache still life.

(It’s best to give an example)

The cold-warm contrast means that when there are more warm colors in the picture, some cold colors should be added to the reflection/shadow part of the still life. This is because of human visual fatigue. Note that this is gouache painting. This is done to improve the saturation of the picture. .The lack of connotation in your children's shoes is probably a matter of saturation.

Also, if the original color of the still life is a mid-tone, its relationship between cold and warm changes with the environment. Then there is the priority of expression. The reason why the lining cloth you mentioned is warmer than the plate but cooler than the apples is because your classmate gives priority to apples. Apples are the main object of painting in her mind. Because apples are perceived as warm in color by ordinary people. So even if The interlining and the general environment are warm, but it is not the main expression--the interlining is the most secondary at any time.

Plates are generally in mid-tones (except for those with obvious coldness and warmth). This type of If an object is placed in a warm color, it will be cooler, and if it is placed in a cool color, it will be warmer. So the painting depends on the mood of the owner, and it does not necessarily have to be cooler or warmer than the lining (I think)

In other words So you definitely don’t understand. I suggest you read up on chromatography and spectrum. There are books on color induction in bookstores. There should be graphic explanations in those books. It doesn’t matter. Your painting method is actually watercolor and traditional Chinese painting teachers. It's pink and porridge. The tablecloth in the front should be brighter, that is, some bright colors with some white powder.

The tablecloth in the back should be more pure, that is, the color is more saturated. The more you adjust it, the brighter it will be. In other words, it will drop

This will give a sense of space

And the brighter the subject object is not the better, the brightest must be the highlight,

Is it bright or not? Brightness lies in the brightness and purity contrast between objects. Only with contrast can they be bright

Darken the dark places, and the bright places will come out
