Imagine a 3x3 grid with cells numbered 1 to 9 from left to right, top to bottom (Row 1: 1, 2, 3; Row 2: 4, 5, 6; Row 3: 7, 8, 9). First, you paint all odd-numbered squares black and all even-numbered squares white. Next, you invert the colors of all squares in the middle column (squares 2, 5, and 8). What are the final colors of the squares in Row 2 (squares 4, 5, and 6)?
