Without cutaway_textures, the surface of the cut take the colour of the 
cutting object.

With cutaway_textures, you get the colour of the main object, AND, 
whenever any two, or more, objects overlap, you get the average of their 
colours.

Corrective :
Use a difference of an object minus any other object from the union that 
overlaps it as the objects to be used in the union.
Trade off : Will use more memory and get slower to render.
