If you paint the cube such that:

Blue and Blue are on opposite sides
Red and Red are on opposite side
Yellow and Yellow are on opposite side

And, since the question didnt state where the 32 smaller could be, Im placing the 32 smaller cubes on the sides with Blue paint. Thus:

32 cubes have Blue on at least one side.
20 cubes have have colors on two sides.
