I don't know the name of it, but it is very pretty. I might have the reason for the lighter color in flowers, one of the sites I surfed looking for my next acquisition explained that the light being bright is needed until they actually start to open then you need a slightly less intense light to maintain the true color of the flower. They also said temp. can do the same thing, and can make some color look very different (eg some reds will look more purplish).
I went looking for the page, here's link
Diagnosing culture problems - Blooming issues. Sorry if against board rules, had some really good info I thought.
