Colouring durable resin with pigment/dye

When I used the powder, I think I let it dissolve for a week or so. Definitely not a quick process. I didn’t think the liquid would have worked so I didn’t try it. Looks like I should have. The dots in the thin part may be from the liquid as I didn’t see dots like that with the powdered flavor. But the powdered needs to have the chunks that didn’t dissolve removed.
