The orange belts would be a great colour swap for Turbo Belts, could you create a separate mod that replaces the green belts, the colour is kind of sickly and this orange is surely more thematically appropriate because Vulcanus

then what would go in place of the orange belt color?
I only have a finite number of color categories to go replacing what's already there in the game.

well it would be a standalone mod so just changing the green belts to orange without adding new ones

Have you tried this mod:

?

yeah a while ago, the way it gives the colour to the belt looks really bad (https://i.imgur.com/wUHzKW2.png) compared to the orange ones from this mod
