Melt ⅓ to ½ of the soap tint with the gel food dye to make a peach tone.
Pour a few shells, then add a little more soap along and a light sprinkle of cocoa powder, melt and pour a few shells in that tone, then added just more soap and make the final shells.
Allow to cool, then pop out of the mold and place in jar with bath salts.
Notes
Sorry, the directions for these are a bit vague. I didn't measure and with using just a small amount of soap, the main thing to keep in mind is a tiny bit of tint will do a lot.
