I have 2 minor requests/suggestions for compatibility with Artisanal Reskins

1. Map the One-way valve to be a tier 0 building so its color can be changed. Here, I've changed the color tiers to be the same as AR default, which gives consistency for the small pumps but not the One-way valve: https://imgur.com/a/sl6Mzu6

2. Not having the icon tier pips that AR adds is a minor downside. If there's a way to add them to this mod's icons that would be a plus.

That's a good idea. Next update I'll add a tint map to one-way valves. As for Artisanal reskins compatibility, I'd definitely love to have that option at some point, but I haven't gotten around to figuring out how it works quite yet. It's on the back burner for future updates for sure, though.
