Don't matter if you've got a BR drawing with the colour stated as a BS or RAL number, in the words of the old song, "It ain't necessarily so"

Years ago had to make some Litter bins for BREL. Manufacture was in house at the fabs firm I worked but the "Powder coated Grey to BS whatever" was by a painting supplier.

Delivered the bins, fine, day later got an urgent to traipse to BREL and two bins at the side of each other showed a distinct difference. Went back to painters to give them a right b********g for wrong colour. Got the BS catalogue out and this and our bin were exactly the same. Had to buy the powder from BREL stores which according to painter, the powder manufacturers product was twice the price of others.

Found out two years later that the Grey to BS bu*****t was the manufacturers "Version" of that spec and had been agreed between the BR Designer and the powder manufacturer.

Take a chip and get it colour matched.

Regards Ian.

There was, sometime ago, a big discussion on one of the woodworking forums as the the correct "Record Blue".

Turned out that the manufacturers had changed it over the years and there is no one Record Blue or any way to find out when the colours were changed.

So any close blue will do.

Ian,

All very reasonable ... but Simon is trying to match his personal interpretation of a photograph in a book.

That's why I suggested a three-stage process

[measure : get a ring-around : tweak the settings]

This should get him 'somewhere near', by including many of the difficult variables.

Another note of caution [especially if using modern water-based paints]: These can be quite translucent, and the colour of the undercoat is important.

I had the car wheels refurbished in 'Anthracite' but, to get the shade that I wanted, it was important to specify 'Anthracite over Black' ... [ 'Anthracite over Grey' comes out looking much lighter.]
