I made a purple cob. See the Malawi cob cureing thread. When I removed the cob from the brown paper, the paper was purple like ink had soaked through. So it's definitely possible that it bleeds.
ur bud doesnt look like its been dyed. I think would be very obvious if was died after the fact. adding color by letting them suck it up like flowers seems redic as i doubt would be worth time or effort. dont trip out man! lol
