new seedlings?

I planted 4 germed seeds (all bagseed) a few days ago and all but one have sprouted and look healthy. I know that one of them was purple and that came from the dankest bag. Two small leaves after the coteyl-whatever have come out, and none of the three are purple. Will it show more purple later or did I kill the dankest?

P.S. Even though I've read up quite a bit, this is my first time grow so I don't really feel comfortable with the process yet...

no the leaves arnt purple the bud is purple

This site is fucking awesome... I get a helpful response in two minutes?!

also from what i understand cold and temps have something todo with the plant turning purlple as well but this is just what i have read thru out the different forums and pages.
