The colored rectangle below is the map of a fancy island. There is a treasure hidden there, but instead of the usual X on the map to depict the location of the treasure you have the following clues instead:
1. The square of the treasure does not have a yellow neighbor.
2. The square of the treasure and its symmetric about the center of the rectangle have different colors.
3. The square of the treasure has a neighbor with the same color as itself.
4. The square of the treasure is unique in its column.
(A neighbor square is one that is adjacent horizontally, vertically or diagonally.)
I attach the image using numbers for the colorblind (yellow is 4).
Find the square of the treasure!
