Thank you Miss Lilly,
Compared to all the other males I've seen, he's been very slow about developing color.
The first three pics he's in his relaxed colors. When he's hunting or on a mission of moving to another vine, his colors become bright blues, reds and greens.
It's just been after this last shed (3 days ago) that he's brightened up. Even then, not as much as all the other guys. I still think he's just a late bloomer who probably has a few more months to go.
