Well the reason's he's colorless was he came from a plane during a time where almost all the mana was gone, thus anyone there who relied on mana used colorless. Dominara was nearly dead at the time of his birth, so I was actually going to make him blue-white but I read more into it, he couldn't have based on lore. It does mean he knows about the great and powerful planeswalkers from before.

The issue with that being, the Great Mending was over a hundred years ago.

Yes but that simply mended the plane, it would have still been a waste land with little mana for next hundreds of years, in the lore they state nearly all the mana on the plane was gone. People barely got by and the's planewalkers used themselves to supplement the lack of mana. It would take thousands of years all the colors to get back to a normal state.
