I must have a thousand giant canyons, I have seen maybe 2-3 ever like this. One was spotted which I wish I would have put aside, but honestly I was thinking maybe it was a fresh molt or whatever and ignored it(I'm not an expert on isopods, just keep several species). Well I put this one aside and it is definitely the permanent color... going to try and find more to separate this morph, it must be extremely rare as I've had these for a few years at least and have only seen it those couple times. These are my go-to Bioactive CuC that I have been using since I got into chameleons... how cool would a big colony of this morph be?!
