So just how does it work?

Thinking logically there must be a a base colour and a coloured lacquar (sp?) over the top, which from certain angles makes it show a different colour.

Whether this is correct or not, I do not know.

I believe it is small prisms in the paint, as the light catchs the prism the colour returned to the eye differs.

Reflex lacquer is all one colour. The different hues you get is from different colour base coats.

The way some of it works, depending on the make of paint used, is to used polarised molecules in the lacquer by using a special spray gun I am told. Its basically a normal sprayer with a magnet that polarises the molecules in the lacquer so it goes on the car a certain way causing the colour difference.

Cool - you learn something new everyday

I was reading an article about the paints a couple of days ago. Apparently some of the cascade type colours are actually clear paint but produce the colours by only reflecting certain wavelengths of light in certain directions.

I found some more information at www.colorshift.com

See www.colorshift.com/pages/how_it_works.phtml for some geek stuff.

I've got no idea if this is the same paint as TVR uses but it was interesting with my science hat on .

Light of differing colours have different wave lengths and as such defract at different angles (which is how rainbows are created), which is why the paint changes colour as you move past, because you are moving through the colour spectrum.

And the critical angle of glass is?

The colour change is caused by the solvents still evaporating and co-incidently being an halucinating drug. This has two effects: first it makes the owner quite oblivious to the £5 grand cost and secondly it causes short term halucinations to anyone within smelling distance who then perceive the colour changing when it isn't. It also explains why not two people can agree on what to call the colours and why a photograph always comes out as a single colour.

All the stories about prisms etc etc are just a cover...

The critical angle of glass is generally demonstrated by Newtons 5th principle, namely arm out, elbow at shoulder height and wrist turning in a toward-face action and is shown to be achieved by the empying of said glass, as shown here -->

If they'd taught that at school I would have taken a lot more notice.
