Description

The dyes named victoria blue are all very similar and they are sometimes confused and substituted for each other in staining solutions, often without any difference in the results. Compare this dye to its close relatives, victoria blue B, victoria blue R and night blue. If one of these three is required but is unavailable, it is worth trying one of the others as a substitute.
