Perhaps. How about this:
The cube is colored on opposite sides the same color, two sides yellow, two green, & two red. Red has the numbers 1 & 3 upon it, green the numbers 1 & 3, and yellow 2 & 2, put in such a way that no two similar numbers are touching one another. The slot below the inscription is painted yellow on the top and bottom, green at the back, and red on both the sides. Both the yellow areas in the indent are marked with 2's, but the green is marked with a 3, and both red areas are marked with 1's.
Sound about right?
