Sometimes my 4 month old, veiled, male, chameleon will turn super bright green one one half and super dark green on the other half of him. Is that something i should worry about???
Hello and welcome to the forums. Is this while he's basking maybe? It will help if you could fill out the "How to Ask A Question" I'll post the link. Just copy and paste then fill in with your answers. Also pictures could really help. https://www.chameleonforums.com/how-ask-help-66/
As noted, the "50 50 bar" look is often just the result of basking. They pick a side and put that to the sun/light, that side goes dark to better absorb the light. I've seen pictures on here of a chameleon who basked near a screen who had a screen pattern on his skin.
