I disagree. E.g. the circles overlapped with green and blue lines look greenish to me, and the circles overlapped with purple and blue look pinkish. If the apparent difference was due to perceiving the lines as a neutral surrounding, the effect should be the opposite: a circle overlapped with green should come across as less green, not more.
I’m pretty sure the effect just comes from half-toning.
Agreed, I experience exactly the same, and is the weakest (read: most easily understood) example shown.
The others are all very good, I really like that I can understand why I am perceiving them the why I do, but despite of that can’t “fix” that perception.
