There are 4 shapes on a 8x8 grid. Which shape is closest to the cyan rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: cyan rectangle at (3, 2)
Distance from target shape to yellow right_triangle at (7, 4): 6
Distance from target shape to red square at (1, 6): 6
Distance from target shape to blue square at (1, 0): 4
Closest shape is the blue square at (1, 0) with distance 4</think>
