If you kill an octopus while it is camouflaged does it remain that color or does it revert to its natural pigment?

The later.  Cephalopods camouflaging abilities are a function of the nervous function.  Killing the animal ceases that function.  If you look around on youtube, there are clips of Japanese fisherman killing freshly caught squids (to preserve freshness) and you can see very clearly the exact moment the animal dies by its color.
