Light colored BRB

This is an old female BRB that I got in a trade about 10 years ago. At the time I had never seen a hypomelanistic BRB and did not suspect that this snake was hypomelanistic. I still do not think it is hypomelanistic but it is as light as some that others consider to be hypomelanistic. IMO the East Bay Vivarium and Darin bell bloodline hypo BRB are the only ones that are definitely a proven genetic mutation. Time will tell whether other bloodlines are actually genetic or just extremes within the normal variation of BRB coloration like I suspect this snake is.
