Using the Multi-Material 2S I made a colored octopus from the Thingverse design:

There are two versions of this octopus, one colored by segment and one colored by layer.
There is also a lizard from the Thingverse design:

It is only colored by segment and the colors are chosen so no two adjacent segments have the same color.

The octopus colored by segment has been lost so I didn't take a picture of it.

Print instructions

If you can print another object at the same time and you don't care about it's color then you can save a lot of filament that gets wasted when changing colors by using it as your Wipe Tower. One file contains the octopus by layer and the other file contains both the octopus and the lizard by segment. If you don't want both segmented prints you can just delete the one you don't want and slice before printing to save time.
