What you are thinking of here does not sound like an anime I know, but a voice simulator program called "Vocaloid". It sounds like the female with blue hair is Miku, and I can't quite recall the name of the pink one.
There is more than one anime like that but I think your talking about Lucky Star
Boku wa tomodachi
It could be Shugo Chara. I think it's Ojamajo Doremi (Magical Doremi). 3 main girls are witches. Red, Yellow, Blue witch outfits.
I don't know about blue hair, but that sounds exactly like the anime sands of destruction. there might be a girl with blue hair but she is not a main character.
Almost every anime series

His favorite color is purple, but he likes girls in baby blue
This depends on the girl. While a lot of girls love purples and pinks, some really like blue or other colors.
