Attempt Number: 6
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To advance towards the goal state, the robot should change the color it is currently holding because it cannot paint the tile directly below with the correct target color, which is black. This will align with the goal state and prepare for the correct painting action.

New State Description:
- Robot1 is on tile_1-1, holding the color black.- Row 0: tile_0-1, tile_0-2, tile_0-3 are clear.- Row 1: tile_1-1 is occupied by robot1 with black paint, tile_1-2 is clear, tile_1-3 is clear.- Row 2: tile_2-1 is clear, tile_2-2 is painted white, tile_2-3 is clear.- Row 3: tile_3-1 is painted white, tile_3-2 is painted black, tile_3-3 is painted white.- White and black colors are available for switching.

Action Chosen:
