Wich kind of bars have you mounted? Fivestars? These are well known for beeing not so tough
However, colorcode of the white parts is "30H", for blue "34S" (on SR41 drumbrake).
Availlable at your Suzuki drugstore
Or: Get these parts to a painter with a scanner/camera for mixing up matching paint.
Cheers,
