I want to be able to judge the overlap of balls by color. [Duplicate]

The overlapping parts are inside two or more balls.

In order to make it visible, you should do the following:
1) Display the sphere in translucent form (so that the overlapping parts inside the sphere can be seen)
2) Display the spherical surface of the overlapping parts in opaque colors (so that it can be seen as overlapping parts)

Wouldn't it be even better if the surface of one overlapping sphere is displayed in translucent and opaque colors of the same color and the color is different for each sphere (the sphere can be distinguished by color)?
