That's right. The sides need to have different colours too.

Alright really stupid question but can you use a mirror cube in a regular 3x3 comp or does it have to have 6 different coloured faces?

3d2) The colours of puzzles must be solid, with one uniform colour per face. Each colour on the puzzle must be clearly distinct from the other colours.
3j) Puzzles must be clean, and must not have any markings, elevated pieces, damage, or other differences that significantly distinguish any piece from a similar piece.
