Here is my take.

As far as I know, nobody has named a boa constrictor mutant gene "hypomelanistic".

Hypo describes any boa constrictor that has less melanin than normal. Salmon is the name of the mutant gene that causes the hypo appearance in a line of boa constrictors that Rich Ihle established.

All salmons are hypos, but not all hypos are salmons. My belief is that Rich named his mutant "salmon" in part to distinguish it from the other hypos around. IMHO, this is good.

My understanding is that sunglow is the combination of salmon and albino. It sounds like that is what you want to produce. If so, pick out a pretty salmon.

Hope this helps.
