The reason they are dark as opposed to blue is due to the humidity. The blue colour comes from a waxy substance on their exoskeletons which retains moisture. They don't need to retain as much moisture when they are in a humid place and so their waxy coat is designed to thin when exposed to relatively high humidity. You could try finding a safe way to incorporate a dessication packet or humidity controlling packet. Maybe add some more sand, sorry that's probably not helpful. Have a small dish for food so the moisture from fruits and veg don't leach into the substrate.
