It's 2017 and Freo are still with ISC. Apparently until the end of the 2020 season.
I wish that the dark purple was much more available commercially for men and women for regular clothing. Not only used by a footy club.
Not even Viv Sports (SA), Sports Trend (Melbourne), Madcore (Qld), or Crown King Sports (NSW) can match the colour shade properly. With a Pantone colour chart, using Freo apparel as a colour guide. PMS 275, 276, or 2766.
Some of Freo's mechandise, such as the scarves have that horrible grape (or merlot grape) purple, or an entirely lighter purple shade altogether.
The purple spectrum is all over the place.
The issue with the colour matching is the texture / weave of each fabric. With different fabrics being used across the range (wool / polyester etc) you will never get an exact match.
Different types of polyester (thickness / weaves) effects the sublimation process in particular. Dyed fabrics (very expensive due to MOQ) will get very close but there will always be a variance.
The ISC products will be the closest to each other but all the cheap "official AFL merchandise" crap is generally all over the place.
