Annuals: What influences Cosmos colors?, 1 by happyNdirt

I had my cosmos planted around an old dead stump. One one side were "Picotee" cosmos, and on the other side of the stump were cosmos "Sensation Mixed". The "Picotee" came up well and bloomed profusely, and the dark pink "Sensation" did beautifully, but there were only a few white or light pink cosmos that bloomed. It seems to be true that the darker color dominated, and I would be interested in all answers on what influences the colors, as well. I even had a strange striped cosmos come up amongst the "Sensation" side of the stump - I dunno where that came from!
