Burn or.....?

[reptileguy112]

I have a Yemen chameleon. It is a female in a 2' x 2' x 4' all screen cage with tons of plants. It has a 18" 5.0 (i think) uvb tube and a 50 watt basking lamp. She can get within 4 inches away from it (her casque) on a vine that is 7 inches away from it. I noticed her spine spikes has turns brown and black and I was wondering if that mean she is burned. Thank you for answers!

I think she looks ok to me. To be on the safe side, I would maybe move the vine down some and if the temps go down too low, then up the wattage maybe to 60 or higher.

Ok, so is it okay if there spine spikes are black?
