What color is generally used as the background when photographing people so that they can be cut out in PS?

Photo studios commonly use monochromatic backgrounds such as blue and green that are in contrast with skin color. Some cutout software has relatively stable cutout effects on these two background colors.

However, any colored background will produce a certain environmental color reflection on human skin. No cutout software can perfectly solve this problem, resulting in the cutout characters being placed on backgrounds of other colors. There are obvious traces of color reflection. White, black, and gray are backgrounds that do not produce color reflections, but such background cutouts are not very realistic.

In addition, it is of course also very important to choose the background based on the color of the clothes the model is wearing. Wearing green clothes and using a green background will definitely not work.

In fact, the purpose of cutting out the picture is definitely to change the background, but changing the background does not necessarily require cutting out the picture. The following idea is provided. This method is more convenient to solve the color reflection, and the effect of resisting the background is more natural.
