fiery brown, this is a tough one.........i,v had all different shades ov so called
fiery brown ranging from bright red to dark brown

you can have a fiery brown dabbler with bronze mallard(brown) with brown body and red body hackle wich some like myself would call a fiery brown dabbler.
really its a choice to the tyer/fisherman what it is, but to simply explain it
it is what it says fiery meaning red hot brown, redish brown
personally i like many shades of fiery brown, claret and also olives
test a few shades on the fish
whatever fishes best is best!
