A Simple Question...or 3!

[Aractus]

Wow, a missed point red herring - and I always thought they were just a myth. The Universe doesn't care how we perceive it or what we do with that perception. There exists a wavelength of the visible spectrum which we humans have agreed to refer to as "blue"; more accurately, it's a range of wavelengths, since there is no single colour blue. What you have to do to get those wavelengths is totally irrelevant. For instance, we only see an object as being blue - or any other colour you care to name - because it absorbs every colour in the spectrum apart from blue, which it reflects.

If you think it's irrelevant why don't you go and ask the next 10 people you see what the primary colours are. If they tell you "cyan magenta yellow" or "red green blue" or worse still "red blue yellow" doesn't that reflect their "world view"? Ask them how to produce fluorescent orange using their primary colours.
