I think to colors should apply to classes. Example, the best red HM would be placed in the running for best of show against the best blue CT and so on and so forth. The IBC has 63 classes I believe.
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.
