"Common knowledge" is, indeed, the right expression. When you want to rub salt into an ignorant peep's wound...

Cheers, tfaerch. Can you confirm Jono's thought that AC140 is a lighter shade than 136?

The beautiful car in the link I posted above seems to have a light shade all 'round - wheels an' all. As that Vert Embrun is the colour I hope to use for my car, I think it's the lighter shade I am after.

So, is that 136 or 140?!

Cheers.
