If a tree falls in the forest and no one is around, there ARE sound waves. But
sound has to also be perceived like color.
There are all kinds of similar waves we can't perceive. They exist of course.
And we can't perceive them.
Graeme has provided text that again syncs up with the other's quoted here about
color and humans:
"By definition humans have no color gamut limitations - anything we can't
perceive, is not a color!"
I can now add his name towards these facts along with Fairchild, Giorgianni and
Madden, GATF, Sharma.
Anything we can't perceive, is not a color!
> Without an observer there are no things at all.
No, there are such things (like the sound waves in the Forrest from the tree
hitting the ground) but they are not observed in the example where no one is
around.

Right. But you above stated first: Without an observer there are no things at
all. Which is it?

No reason to doubt what so many actual experts in the field have told us. No
reason to doubt climate change or believe it's a hoax from China. There's
plenty of science to observe if you're a science observer. I recognize not
everyone is.

It's sensitive to something.

Color is the excitation of photoreceptors followed by retinal processing and
ending in the our visual cortex, within our brains. The eye is part of this
process but only part.
