If we eliminate the hidden faces of a sphere approximated by polygons and color all visible polygons with the same red color, we will obtain a red circle! This is because our perception of the third dimension is greatly improved by the reflection of light. In the case of a sphere, the different points on its surface do not reflect light in the same way if there are point sources of light. This means that the sphere must not be colored with a uniform color.
