You will hopefully not paint the flame tank set!
Another complete set good to have for a quick swap.
Briar Brown, mostly spelled Brier Brown which must be wrong is very dark, difficult to see it as brown, right?
The old bikes I have seen have not been brown at all, as a strange color you'll get when mixing all old paint cans you have into one
The new (K1) Garnet Brown tank from Yamiya look good.
I painted a tank with Peugeot Cupid Brown Metallic after I heard from an earlier owner that the bike, CB750 K2 was brown from the very beginning, Briar Brown.
When I saw a sparkling brown metallic Peugeot 3008 SUV in the sunshine in Spain May 2018 I found it to be next color!!
K2 stripes on as well.
Brown metallic seems to be more popular on cars the last years. Mercedes and Volvo have nice versions of brown. Maybe Opel too.
