Yeah. I figured that much out by pure chance.
Now I'm struggling to get my avi to change. I click "save avatar" it says my avatar is saved, but nothing changes. Like...I click around, but my avi is still the same as before. All black shadow.

It's just extremely tedious (especially on mobile) to not start out with at least a few pre-made skintone base items in a few shades. Like, I get that I can dye it myself, but why not start with a few base options and then we can customize later. Just so it's a tiny bit easier to get started rather than bumbling around and hoping we stumble onto something helpful?
