Four cubes need to be stacked on top of each other.
Constraint 1 - Each of the four cubes is expected to be made of same four colors
Constraint 2 - When stacked on top of each other, all the 4 vertical sides should contain four different colors each
Constraint 3 - No two cubes should have colors arranged in the same pattern. i.e.,
R-G-Y-B cannot be stacked on another R-G-Y-B but just rotated by one side to get different colors vertically.
I have used 4 cubes (#1,2,3,4) with colors (Black - Red - Green - Blue)
The patterns for each of the four cubes are:
#1 - Black - Blue - Green - Red
#2 - Black - Red - Green - Blue
#3 - Black - Green - Blue - Red
#4 - Black - Red - Blue - Green
