Espacially during implementation, we move back and forth between the Sandbox and the Prod environment. The colour scheme is changeable for the Learner Portal but not for the Admin Portal so we can easily see which one we are in and avoid major boo-boos in Prod. It would be nice to have this same flexibility in the Admin Portal.
Our previous LMS had TRAINING in the header as the only way to know which environment you were in. Let's just say that was less than ideal.
