Attempt Number: 2
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
The next best action is to change the color to black, as the next tile to be painted (tile_1-4) requires black. This aligns with the goal of alternating colors.

New State Description:
- Robot1 is on tile_0-5, holding the color black.- Tile_0-5 is occupied by Robot1.- Tile_1-3 is painted white and is no longer clear.- Tiles tile_0-1, tile_0-2, tile_0-3, tile_0-4, tile_1-1, tile_1-2, tile_1-4, and tile_1-5 remain clear and unpainted.- The colors white and black are available for switching.

Action Chosen:
change-color(robot1, white, black)
