Action Reasoning:
The robot is currently holding black paint and can paint the tile directly below it. Since tile_3-3 needs to be painted white, I'll switch to white to prepare for painting tile_3-3 in the next step.

New State Description:
- Robot Position and Paint:   - Robot1 is on tile_2-3, holding the color white.- Tiles Status:   - Row 0: tile_0-1, tile_0-2, tile_0-3 are clear.  - Row 1: tile_1-1, tile_1-2, tile_1-3 are clear.  - Row 2: tile_2-1 and tile_2-2 are clear, tile_2-3 is occupied by robot1.  - Row 3: tile_3-1 is painted white, tile_3-2 and tile_3-3 are clear.- Available Colors:   - Black and white are available for switching.

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