I think those of you that find reds and blues boring may be a litle hasty. I used to think they were boring too but you haven't seen a blue or red until you seen show quality ones in person. Good ones are so pure and classic and pictures just don't do them justice.
I think the longer your in this hobby the more you can appreciate every color and see beauty in them all. I never liked whites and swore up and down I'd never breed them but then I saw a white PK at my lfs and he was just so pretty (despite being blind in one eye) he completely changed the way I see whites.
I agree with Dragonlady a healthy betta is a beautiful betta in my book.
