<think>Target shape: orange square at (6, 1)
Distance from target shape to yellow square at (2, 3): 6
Distance from target shape to green rectangle at (2, 5): 8
Distance from target shape to purple square at (2, 7): 10
Distance from target shape to cyan rectangle at (5, 1): 1
Closest shape is the cyan rectangle at (5, 1) with distance 1</think>
