weird purple/blue pigment in the leaves

[resinator]

plant is gone a weird purple/blue pigment in the leaves,i recently put a few plants that hermied on me out in the ground then over a couple of days the leaves changed to a bluey purple colour,

any idea's i dont know anyway what could be causing this. i do have a pic of this in my phone but cant get it posted for some reason.
would appreciate any ideas on which scenarios could cause this change in colouring

What are you low temps there? Low temps will cause purpleing of the leaves. ;-)
