Bingo!
So it seems that whether colours exist or not is irrelevant, but that we have common terms of reference with which to communicate.
All well and good (and I think we're touching on subjects that bear further consideration later), but I still am tempted to ask.
Do colours exist? Do you believe there is such a thing as red? As blue? As yellow? Does the object have an inherent characteristic,
independent of its observation by a conscious observer, that can be described as a colour?
I think not.
We can say "Such an object is 10kg in weight" and (ignoring the issues of different scales of measurement) such a statement is true. But how can we say "Such an object is red"? The only reason we believe it to be red is because our mind interprets the light reflected from that object as being red.
