Walk 5

Homage to the self-avoiding walk on a 5x5 grid. In each of the 100 cells, the boundary between the black and non-black areas is the walk. Four types are highlighted by their coloring in each quadrant of the figure. A fifth type is left "hidden" for you to find. In each quadrant, the cells are arranged according to, and unified by, the walk in the center of the quadrant, highlighted by its inverted coloring. Although it may not appear so, everything in this image was placed deliberately.
