As noted by Luna, we can't use the house colours as they are used for other jobs.

The problem is that we don't know enough about the other schools/geographic placement, to be able to make a whole univsers.

Hogwarts/diagon-alley/hogsmeade/UK is what the 7 books are about. Yes, we do hear about Bauxbatons and Durmstrang, but not nearly enough to be able make an immersive universe.

We've thought of this before, but decided not to do it, as the user might not get the wand he/she wants. That's why you can choose yourself, when you buy.

This idea has now been started.

But we need your help for this to be a reality.
