You are very optimistic, nice
Yes, it does, but sometimes it’s also all thrown over board... flat earth... round earth... earth in center of universe... earth rotates around sun... who knows what quantum mechanics will do...
If this were so - and I am not saying its not -, then everything, not only Redness, can only be experienced because it is in the mind.
Now replace the word mind with consciousness - and leave out the word “in” because if everything is in something there is no way of telling if there is anything beside it: It can only be experienced because it is consciousness.
Let me try to explain in a slightly different way:
It's like stating that "I experience/'am looking at' the universe" implying that I am separate from it... but, at the same time, there would be no universe if we remove the content - we cannot remove planets, stars, gas clouds, humans, not even a grain of sand and still have the universe left - the content IS the universe, no content, no universe. As such, every apparently separate thing is simply again "made of" the universe - and if "I am looking at the universe" then the universe is, in fact, looking at/experiencing itself.
