In my experience males are some shade of brown, beige, or sandy colors. Females are usually a shade of green/olive and whites. One of the females I have was a brilliant mix of yellowish & green, with some red, black, green, and brown right after I caught her. After she laid her first clutch of eggs (and acclimated to captivity), her colors calmed down to the typical greenish-whitish. In my experience the males grow substantially larger than females.
These are my first clutches of Oustalet's, I have lots of breeding experience with Veileds. I have a few wholesale contacts in SoCal, I was going to call them and offer them most of the hatchlings, plus try my luck at few local pets stores, and maybe craigslist, but I don't expect to sell many that way as they aren't as popular as Veileds. I didn't plan to sell them here or elsewhere online, as selling by onesies and twosies with packing and shipping gets to be a headache. Having said that, I will post when they start hatching, and if you are interested in one I'm sure we can arrange something-
