Rambo has allways fired up when I take pictures of him. I thought it was just the phone ( It is black )but yesterday I had on a black glove and tried to feed him a dubia,he went crazy and flew up the cage,went full blown color and was hissing and gaping! I felt so bad that I didn't even think about taking pictures as he never looked so good. I know some colors set off chams and I guess one of his is BLACK
