What's the point of colour?

Colour affects our responses quite significantly. Proven fact.
Now did nature develop colour that way or did it develop us that way? Oh crikey, my head hurts now.  

Lays down in a blue room 

Is the room blue, or do you just perceive it to be blue?

More to the point, am I the only person in the universe and just imagining that everyone else exists?

We may all be alone in our own individual universe and the people around us may just be a figment of our imagination.

My head hurts as well now. Better go and lay down in a room of any colour of the electromagnetic spectrum...

We're merely discussing life's philosophical matters.

I shared a bed with a women last night.  She thought the colour of the walls was magnolia.  I thought they were insipid

But how do you know that you are getting 'it' and that 'it' is not just a figment of your imagination?

I disagree with you there Intermanaut.  The whole point of Belgium is their chocolate

SuperCaz - how can you forget the beer?

Because I am a cider drinker and they are not famous for their ciders

Belgium beers very good.

There are lots of things for which the point of their existence is not immediately obvious. Belgium, for example.

The European Parliament?

Errrr...point taken. We could manage without Belgium.

You are Jeremy Clarkson and I claim my five pounds.

More to the point, Belgium makes the best chocolate and the best beer.  Beer and chocolate are two of the most important things in the world, therefore Belgium is one of the most important countries in the world.

I've also often wondered if what I see as green is the same as what anyone else sees as seen. It probably is, but maybe not the exact same shade. I can't think of a any way of proving it.

Most people are trichromats, and have three different cones in their eyes. Some people are dichromats (colour-blind) and there's some evidence that some people are tetrachromats. These groups of people will all experience colour differently.

Even amongst trichromats, colour may be to a certain extent subjective, so probably we don't all see exactly the same thing.

Oh, and this colour survey is pretty interesting too.

Colour doesn't exist 'out there'; colour only exists in conceptual minds.  What actually exists is electromagnetic radiation, of which we percieve a small spectrum (called 'visible light'), and this small spectrum of WAVES enters eyes, and if there is the correct nervous system behind the eye, the BRAIN will create colour; somewhere near the back of the brain.

It's the same with sound; external to the brain is mechanical pressure waves; once these hit an eardrum with the correct nervous system behind it; sound is produced in the mind.

You could say that we make the Sun shine!

Interesting eh?

It's a very difficult philosophy to disprove.

Anything which enters the mind is subjective.  Even if we look at the same car, we will each perceive that car differently.  You may see a 'cool car' and I may see a 'chav car'.  Same car, but we perceive it differently; albeit at a very subtle level.

Sorry, I like philosophy.

See, I thought that I may be on to something. In which case, why am I typing this, as there may be no one else out there to read it.
