Nope. That's called buff, and it occurs quite a bit, but is not at all desirable and it's a disqualification. The reason being is that buff Tollers can't toll/lure ducks for some reason. The ducks toll for a flashy, bright red coat best.
Tollers also appear in tri-colour as well as sable every so often too. Both of those are equally as undesirable as a buff, though I'm not sure as to why. Those two colours aren't very common at all though.
