[ExI] Nobody knows the true colors of things, on this day of color.

[Brent Allsop]

Hi Rafal,
So when you say "colors are concept created by our brain to label objects"

What do you mean by "label"?  As in, we label a redness quality,
representing knowledge of a strawberry as "red"
Or are you saying colorness qualities of our knowledge, which are
representing the properties of the surface of the strawberry, are labels of
something?
