4 2x2 blocks
Make sure you don’t have any blues in the same rows or columns.
Because yellow is already in this block, you will be able to put it in all the remaining 2x2 blocks.
To make sure you are doing things right, you can place one orange, then move onto another color and come back to orange later.
Make sure you don’t have the same colors in any row or column.
