There are 4 shapes on a 8x8 grid. Which shape is closest to the pink square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).

Distance from target shape to orange right_triangle at (0, 6): 3
Distance from target shape to cyan square at (4, 4): 3
Distance from target shape to gray rectangle at (6, 5): 4
Closest shape is the orange right_triangle at (0, 6) with distance 3</think>
