The fact that, Bob, you report seeing with a stronger "blue" intensity after your cataract removal indicate that your brain does receive the new retinal information, but how is your brain "adapting" to the change is my question?
I didn't subject myself to laboratory analysis, but before the ops, I preferred sunglasses with a slight blue tint, while now I prefer sunglasses with a slight yellow tint. You could do some experiments on yourself by wearing a pair of yellow tinted glasses with one lens removed (or replaced by a blue tinted lens). How does the brain adapt to that? Is one eye dominant? Or does the brain average the results out?
From my reading on the subject, it seems that color vision is far more variable than some would have us believe.
