These settings can be used if the desired staining is not achieved through the
decolorizer settings alone. Once you have found the decolorized setting that works,
you can adjust the amount of Crystal Violet (C) and Iodine (B) according to 3
settings: Low, Default and High.
Recommended setting is Medium.
A setting of reagent C High and reagent B High will produce darker Gram-positive
organisms.
A setting of reagent C Low and reagent B Low will produce lighter Gram-positive
organisms.
