Blue vs. red gums ?

[aeolis23]

Hi

I am keeping pygmy chameleons at home, and I noticed that sometimes their gums are blue and sometimes pink/red.

I didn't notice if it differs intra-individual or inter-individual, as it's been a long time since I noticed the blue mouth with another pygmy than the one I saw now with the red mouth. Never payed attention too it anymore since that one time, untill now when I just saw someone posting a picture online of another blue mouth.

Could someone explain this to me? And are both colours healthy?

Anyone who can explain this to me?

I noticed the same with my panther but with other colors. When I got him he seemed to have mostly yellow gums but they're pink like most animal's

My pygmys have black mouths. I've researched this and found its due to the fact that they don't want to give them selves away while 'shooting' at prey items.
