Locale- ambilobe, tamatave, sambava, etc. Those aren't random names. Its the name of the town from where the panthers come from. Nosy Be's come from Nosy Be in Madagascar.
Some take longer to get intense colors that others, but they all eventually do! My ambilobe took foreeeever to get bright colors, almost 7 months, while my Nosy Be was a light blue the day he came out of the box at 3 months old. So it's different for all of them but they do all eventually color up to their full potential.
Yours looks like a cutie! I love the little baby chameleons.
