That indeed removes the impression that the triangular edge parts of 4 and 5 are cells in themselves, which diagonally border a3 and h6. For the same reason I had used the same special color for all of 4 and 5 in the Interactive Diagram. In the rectified representation a4 and h5 are not distorted, and the shape is enough to suggest that they do form complete squares partly hidden under 4 and 5.
