Are purple poinsettias real or have they been dyed?

There are real purple poinsettias that have been cross bred. There are now several different colors which includes the purple.





I still like the red best of all.





There is also a white poinsettia that a nursery painted. Here is a pictures.....I don't think they are very pretty:

The purple one I touched in Wal-mart the other day was most definitely painted as the paint came off onto my fingers....
