Why do the tones seem so different?
1. They have soft edges, and soft edges usually belong to shadows.
2. Those edges are parallel, and cast shadows from the sun on flat surface are parallel.
3. The tones of adjacent colored squares shift gradually in value to an equal degree, just the way shadows do.

Wow. Powerful illusion. I am not sure I understand your three points. It would help if the figure was annotated to highlight what precisely each one means.
Interesting optical study
