Hmmm, can an Audi look like a Chevy?
Preben has given you some good advice. But my question above is meant to point out that all products, including Learning Management Systems, take on their own look and feel. If you want an Audi, don't buy a Chevy. (Of course, Moodle is free.)
Having said this, I do want to emphasize what Preben has advised. Moodle can take on many different looks. In my own case, I use the base "boost" theme and modify its appearance by adding
CSS, something that anyone with some CSS knowledge can do. And yes, you can install one of many third-party themes to make your Moodle look different. There are free and paid-for themes. And, if you prefer, you can have someone develop your own custom theme. So with Moodle, you have a lot of flexibility.
