Is Dinafem Blue Hash Purp?

I see that Dinafem Blue hash sometimes grow purple. Is it always purple? Is it just by chance? or is it by a certain way of growing? If so, how? just wondering this because I have a blue hash in veg right now n thought itd be cool to have some purp haha. any info is good. thanks

i give purple strains a big PK boost the last 2weeks that i feed in flower..seems to do the trick, alot of people drop the temp to get purple strains to turn more purple or turn purple faster.
