If you're making paint of one sort or another and you need a pigment that is easy to mix into that medium, Cal-Tints can fill the bill. These are pigments with broad compatibility, (i.e. they mix with a lot of different binders). In fact, we've used them in polyester resin, epoxy resin, latex rubber, acrylic paint, varnish, and even plaster. About the only thing they probably won't work in is polyurethane resins and elastomers, and maybe silicones. Available in 16 oz. bottles.
