Grey?

They are nocturnal, so you might not see a lot of action during the day.

You will if you throw some crickets in there. They are one of the few animals I know that can go from a dead sleep immediately into feeding mode.

hmm do you think it lessened the chance to mess them up if i did it slowly. I had thought about this and changed it over the course of a week in increments.

I don't think it matters. Nocturnal animals are supposed to be noctural, so I don't think its a good idea trying to change that. Let them be active when they are supposed to be.
If you want to experiment switch your own days for nights and vice versa. Then tell me how you physically and psychologically feel. I gurantee you will feel like ****. I know from personally experience.
