There are 6 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).
<think>Target shape: pink square at (0, 2)
Distance from target shape to blue rectangle at (7, 6): 11
Distance from target shape to red right_triangle at (2, 2): 2
Distance from target shape to gray square at (6, 3): 7
Distance from target shape to brown rectangle at (1, 4): 3
Distance from target shape to cyan square at (6, 0): 8
Closest shape is the red right_triangle at (2, 2) with distance 2</think>
