As I was developing my first mod, one that would add multiple colors for military and spec-ops gear, I came to an issue regarding how these might be crafted. Normally, white variants of barricades can be dyed using flares, but this leads to an issue if one wants to create black furniture, which as far as I know is unobtainable normally. There is the possibility of using smoke grenades as a source of dye but having recipes for both flares and smokes would clog the crafting menu.
My solution would be to allow players to craft Dye Bottles from items like Flares, Smoke grenades, Classic Vehicle spray-paint, and Paintball Hoppers. This would allow for dyeing system to be a little more consolidated and to add more uses to the new Dye Vat.
(Also maybe let people create paintball hoppers using a bottle of dye and some metal scrap, making paintball much more accessible in survival? Just another suggestion.)
