Ultramarine blue is a classic true blue color in soaps.
Using Ultramarine Blue:
Cold Process Soaps: Add to oils and then add to soap.
Melt and Pour Soaps: Add to a bit of glycerin then add this mix to your soap base.
Ultramarine Blue can bleed onto a washcloth, although it should not stain. Less is more when it comes to this color.
