I know, I just wanted to make sure I understood what the four squares were supposed to accomplish.
What confused me is that
here on the page I read about the squares it says
The interesting feature of this step is that the squares need not match in colour.
then it says
All 4 squares must have one color in common. In the above example, orange is the common color.
First it says they dont need to match, then it says they do.
