If your caterpillar turned brown it might either have died or, most likely, it pupated and started to turn into a butterfly or a moth.
Usually if it is a dark brown and still caterpillar-shaped, it has probably died, but if it is a lighter brown or reddish colour and has a different shape, it is most likely starting a cocoon.
Your caterpillar has a few stages before it'll die or go into a cocoon
when it's dying it sit in one spot for days. when it's getting ready to go into a cocoon it'll walk around and eat and seem more lively then ever. Your caterpillar is growing up he isn't changing colors he's shedding his hair (which means he will within this week go into a cocoon)

Not a Hawkmoth, this is a swallowtail butterfly caterpillar.
grey moth
the girl caterpillar will be brown and have large ''eyespots''. the boy will be green and have smaller ''eyespots''
The caterpillar that is green with small fake "snake" eyes is the Spicebush Swallowtail Caterpillar. This caterpillar will turn into the spicebush swallowtail.
That's either a snake or a caterpillar. I hope it's a caterpillar.
the caterpillar will turn into a small brown pupa hidden in the leaf which will then emerge as a small brown moth.
The puss moth caterpillar has a furry light brown color and will turn into a puss moth. They are one of the most toxic caterpillars. Another furry caterpillar is the wooly bear but it is brown and black and it turns into a wooly bear tiger moth.
An anole can turn green, gray, black, and brown.
