Plus a prism should be clear so that all the colour spectrum can be refracted through it when white light shone on it....the colour being red will prevent the red colour wavelength being shown!

Pyramids can have various numbers of faces. A tetrahedron, or triangular based pyramid has 4 faces. A rectangular based has 5, pentagonal based has 6, a circular based (or cone) has an infinite number of faces. |

It's very hard to make a three dimensional object with less than three plane faces (sides).
