There needs to be excess Bromide to ensure good re-halogenation, this usually meand the same weight of both. If there's insufficient bromide you run the risl of forming unstable silver ferricyanide complexes which may wash out before imersion in the toner itself.

If you want a warmer tone use Sodium Chloride instead of the Bromide. Or better still use a Thiourea toner for greatest variations in warmth.
