Purple sectorial chimera

OutdoorBlueberry AK. I noticed it’s getting dark purple around the flowers and sugar leaves too. Is this common?

Havent seen this in black, but i have seen some photos of similar thing but white instead of black, but i think thats for different mutation than this. Saw some guy on instagram who tried to stabilise that white trait.

Anyways it looks cool! Keep us posted if it does more of that or if you make seeds and they show the same trait
