Is there a such thing as an orange valium?

Well I found a little box in my sisters room, it had two pills in it. One was blue and it said dan and I know that is the generic of valium but the other pill in the box was orange it has no imprints, it looks pretty old like tha imprint got scd off. Thats why i was wondering if it is a valium too. Or if it could be a valium.
