There are 6 shapes on a 8x8 grid. Which shape is closest to the orange square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange square at (6, 0)
Distance from target shape to cyan square at (7, 5): 6
Distance from target shape to blue square at (3, 0): 3
Distance from target shape to yellow rectangle at (5, 0): 1
Distance from target shape to gray rectangle at (7, 2): 3
Distance from target shape to red square at (0, 3): 9
Closest shape is the yellow rectangle at (5, 0) with distance 1</think>
