No Loki, a friend of mine on the WWI Modeling List years and years ago made the suggestion that RLM02 as a similar color, and in the years since it has been picked up by many, many people as some kind of gospel, and has grown into a monster. (He has gone on record time and again to clear this up, but to no avail.)
Is it similar? Yes. Is it dead on. No. Should you use it? Up to you.
