Getting Bright Red Color in Vat Dyes



One solution proposed is to mix Brown R and Red 6B.

Brown R chemically has an excellent wash fastness and dry rubbing fastness of 4 and light 6-7. However, its color fastness to rubbing in wet is only 3.  Source

Red 6B chemically also has an excellent wash fastness of 4. However its dry rubbing is only 3-4 and wet rubbing is only 3.  Source

Thus it is difficult to obtain the good rubbing fastness in this combination of dyes.
