Can I color the resin?

Yes, and there are many way to color Little Windows brilliant resin, depending on the look you're going for.  Dyes, glitters or pearl powders, metal flakes or mica, oil paint, and acetate.  Since our molds are so reflective, I prefer using clear acetate in the color of my choice, cut a piece to fit snug at the bottom of my mold, then cast the piece. The molds will reflect whatever color or texture you put at the bottom of the resin, up and around the sides, making it look as if the piece is colored throughout. If I need to layer, I'll let the first layer with acetate set up, then add more resin and elements on top.
