<think>Target shape: brown square at (6, 2)
Distance from target shape to blue rectangle at (1, 2): 5
Distance from target shape to yellow rectangle at (2, 6): 8
Distance from target shape to pink square at (1, 0): 7
Distance from target shape to cyan square at (3, 0): 5
Distance from target shape to green rectangle at (7, 6): 5
Closest shape is the blue rectangle at (1, 2) with distance 5</think>
