In the real world, there is no light frequency associated with “green” and only “green”. There are lots of situations that will cause me to experience an object reflecting a single light frequency as different colors.
For example: change the background color or design an elaborate pattern in a picture. There are some freaky things our brains can do (and can be tricked into doing).
(nods) Or just shine a red light in my eyes for a while, then turn it off.
It’s not even particularly freaky, it’s just that we’re accustomed to treating certain aspects of our perceived environment as primitive atoms of perception when in fact they are the outputs of complicated heuristics that aren’t perfectly calibrated for consistency.
Freaky as in an incredible feat on the behalf of our brain to be able to reconstruct 3d images from subtle clues like relative shading. Giving deceptive input to make it perceive color incorrectly is just a harmless side effect.

Ah. Yes.
As optimizing systems go, we leave a lot to be desired, but for self-organizing soup we’re pretty impressive.
