The complete conditions for this scrambled cube can be described alternatively as the following:
1. Each face has less than 3 squares of the same color, which leads to
1a. Each face has 5 or 6 different colors.
(2. It's a huge bonus if the same-color squares are not adjacent to each other. In other words, they don't share an edge.
2a. It's even better if they don't share a vertex!)
