Yes, for most jobs. Very close match (ΔE 4). Old Wood is a little lighter, warmer than RAL 7027 Grau.
The same difference applies the other way round: RAL 7027 Grau is a little darker, cooler.
ΔE is the colour difference between our two swatch estimates: under about 6 is close, over about 15 is loose. Real paints also differ in finish, coverage and how they thin, so test before you commit.
