I wonder how much of this is ‘seeing’ and how much is emergent in the brain due to the drug. I suspect the latter, but that’s just opinion.

“how much of this is ‘seeing’ and how much is emergent in the brain”

Yeah… it’s gonna be hard to distinguish those in the best of circumstances.

Seeing is also an illusion by the brain, all colors are in your head.

I realise that, I’m just speculating on when the effect emerges. Whether it’s because of changes in the cones (which are the tips of nuerons) or a later emergent property.

Most likely an emergent property. Psychedelics affect serotonin pathways, I don't think that cone cells and the first layers of neurons behind them have serotonin receptors.

"Seeing" starts pretty much at the retina level and along the optic nerve. Lots of signal processing and data compression going on there. I wouldn't be surprised if hallucinogens affect those areas as well.
