When making the puppet in Photoshop, some layers were marked green by the program. Why?

[judyl50412176]

Hello! I am trying to make changes on my puppet and when I reopen the psd file, I noticed that some layers were marked green in the Photoshop. Can anyone tell me why this happened?  What's the difference between the ones that are green and those that are not?  

When checking with the Adobe puppets (demo), I noticed that none of them had green layers. I am wondering if I did something wrong? 

Thank you in advance for your help!

Is this your own file or ? I cant see what layers are green... but its possible that whoever built the puppet color coded some of the layers in Photoshop to keep organized possibly?

Layers can be color coded....

hope that helps
