The other day someone told me the everything in the world is the colour gray & its our brain that makes us see things in colour... Is this true?

It is our brain that makes us see in colour, but also our eyes, and the properties of the object we are looking at.
Natural visible light from the sun appears white, but it is really made up of all the colours of the rainbow: red, orange, yellow, green, blue, indigo, violet. Each of these colours has a different wavelength.
Every substance that we see as having a colour is made up of a material that absorbs certain wavelengths and reflects others. This is what gives it the appearance of colour.
So something that looks blue, is absorbing all the blue wavelengths in natural light and reflecting all the other colours/wavelengths. Our eyes pick up the reflected wavelengths, and our brains interpret this to mean the object is blue.
There is a really clear website here as a source which explains this well.
Cheers!

This is going to be a bit odd:
When someone tells you that they like the beautiful blue on the 67 mustang gt. What they are really telling you, is they like the color w/o blue in it. How we part colors is a strange idea. Black and white are not colors, but shades. Grey is the possibilities you get when you mix thoes shades. Which you can come up with many different forms of grey. However grey is perhaps the absence of color. Blue is what we call the color with everything in it, BUT blue. The world is black and white metiforically speaking( to me ofcourse) But Colors are very real.

It could be as nobody will ever know that. I suppose as a rainbow is created through sunlight & raindrops & white is created through a spectrum of colours so could colour be created in the brain to make us see something completely different. Mmmmm! a brain overload question.

No it's not true.
Colour is the wavelength of the light your eye detects (and many it can't). The universe is very colourful indeed. However your perception of colour is different depending on the person. Pehaps that was what your friend was going on about.

To answer your question:
Recently on holiday in Greece I was walking along a nudist beach.
I approached two women who I thought I new,
One said, "Is that Willie Gray"?
The other one said, "No it's just the way the light is hitting it".

I think it safe to say its a variation of colours

It is if you live a boring lifestyle or maybe going through a bad patch in your life, like a family bereavement.

No. The world is full of color. Not only the ones we can see but also ones we can't.

What you heard was a description of the average color of the universe. not a single point like a star but the accumulation of blacks, blues, whites, etc.
