It's not that cut-and dried, I'm afraid.
It used to be that the traditional white/pink/mauve hybrids were typically winter bloomers, as they tend, as a group, to respond to cooler temperatures. Those in the red/orange/yellow range tended to be summer bloomers.
Hybrids in which amabilis, aphrodite, schilleriana, equestris, stuartiana, and the like - the "thin petaled" species - are used, tend to be with cool responders. Stuff like amboinensis, cornu-cervi, gigantea, mannii, mariae, and those thicker-petaled plants tend to be less strict about their blooming periods, sometimes remaining inn bloom essentially all the time.
Considering the complexity of hybrids and colors these days though, it's hard to really categorize them all that well.
