Breaded dragons change their color depending on several things.. Sexual maturity, heat change, diet change, mood, and humidity levels.. My beardie Yoshi, looks alot like your Orion, and she somtimes gets those exact same yellow markings on her head, and legs..
I believe your beardie is in perfect health, just watch her appetite. Keep an eye on her, if she starts getting lathargic dont hessitate to take him to your local Herp vet..
