I have a samples book that shows regular RAL colours,but also loads of others comprising 2 numbers,1 letter,then 2 more numbers,eg,12 c 39.
How are they used/compared/ quoted,do paint suppliers recognise them? Thanks.
Or have a look at the similar colours to the one you want and see how the codes vary.
If they are close you could type a few into google and see if they correspond to a BS standard or something
Or just ring up the paint supplier and give them the number you have got and ask,
Ie. Hi, can I have 2 litres of 12C39, is that a shade of Green? Thanks..
They will soon tell you if they need any more info than that
