Your irises contract to protect your eyes from damage from overexposure. Contracted irises mean less absorption of light which means less precise vision in general. Likewise, more white light in the area washes out and fades colors because of its higher visibility creating that contrast.

It also is directly linked to the light receptors, cone cells for example red and other color perception is being drained, thus more blue color.

Respectfully, none of these statements after the first sentence is correct. When going from dark to very bright, it takes the iris and, to some extent, the retina, some time to adapt. During this time the light will saturate the cones in the retina and thus colors will be washed out. Once adaption is settled, the iris is contracted, and your vision will be especially good, both sharpness and color perception will be optimal. Bright white light is the best for seeing the colors of objects.

But that sounds exactly what I was saying. Where is the disagreement?

“Contracted irises mean … less precise vision" it means more precise vision. “More white light washes out and fades colors” no it enhances colors after adaptation is settled. The lack of color is due to retina saturation. “because of [more white light’s] higher visibility creating that contrast” this doesn’t make sense. I think you meant brightness not visibility. And I think you meant saturating colors not creating contrast.

When the cones get over stimulated/saturated with red and green (or should I say when the red cones and green cones get over saturated/stimulated) (after being in the sun out in he garden say) and we come inside and it seems a blue hue, is it a similar nerve impulse “numbing” that we experience when we chew gum? (As in after a while the flavour wears off, but take it out, have a drink of water, then put it back in and chew it the flavour comes back)? I understand one is to protect the nerves (cone situation) am the other is to detect flavours behind overwhelming ones (mint gum), but I wonder if the impulse is blocked at the eye/olfactory, or the brain itself that actually blocks them out?

This isn’t related to my field at all, but my observation is that of it is bright enough and your eyes are closed you can end up with an afterimage in the complimentary color that spans your whole vision. Is that what you are describing?

Nope. Let's say you are on the beach, laying down facing sun with closed eyes. After 5 minutes you open your eyes and you see the sand and the sea. Usually they are yellowish (sand) and blueish (sea) but you can only see some shades of gray of very pale yellow/blue. This is what I experience, I've never seen complimentary colors
