Parent State ID: 91
Action Taken: change-color(robot1, white, black)
Action Reasoning: The current state has Robot1 on tile_1-4, holding white paint. The last action was a color change to white. According to the strategy, after a color change, the next step is to "paint-up" the tile directly above. However, tile_0-4 is not painted yet, and its paint color should be black as part of the alternating pattern. Therefore, the correct action now is to change the color back to black before painting the tile above. This aligns with the goal of achieving an alternating pattern starting with black.
State Description: Robot1 is still on tile_1-4, but it is now holding black paint instead of white. Tile_1-4 remains occupied by Robot1, and tile_1-3 is clear.
