BS or RAL code for CIE tan/orange

[Mayner]

I had some CIE tan aerosol mixed a couple of years ago , but got an orange peel effect when I attempted to spray a coach tonight.

I am not sure if its a problem with the spray can nozzle or the paint mix

I had the paint mixed to a RAL code but mislaid the colour reference.

Does anyone know whether a BS. or RAL code exists for the tan used from the 1960s to the 80s

Thanks
