Dyeing tempest fabric (Patreon)

Dyed a whole bunch of purple for Tempest today. Using the following combos: 

Fabrics: 

Mauve 

Raspberry 

Dye: 

Idye poly - 1 pack purple, one pack pink, 1/2 pack black. 

Dyed between 2 minutes and 20 minutes. I always get such varied results as each batch of fabric is dyed. Each 1/2 yard of fabric takes out a certain amount of dye, making it less potent in future dips. 

Struggling to pick which one is most accurate to her, since her purple varies so much from Mac to PC (from a fuchsia purple to a duller blueish purple). Anyone have the physical art book that can chime in?
