Breeding isn't like painting...you need to understand the basic genetics of the colors.
As far as purple....it's very hard to produce but luckily I am spawning a purple pair this coming weekend hehe.
Who am I? Well I am a Junior Member of the International Betta Congress and a breeder of white HMPKs, red dragon HMPKs, black/red dragon HMPKs, metallic multi HMPKs, blue masked HMPKs, and now multi color HMs. Soon to add black HMs. I will be showing in New Breeder class in fall of 2012.
