Thanks for playing!
For anyone interested...
OK, GW's Bestial Brown used to be paler and less red than the version they
currently sell.
Vallejo's Beasty Brown is a perfect match for the old version.
Not actually a problem for what I want it for - the bottom coat on flock.
You can also try this colour comparison doodad. Go play with it it's
awesome.
