Opaque Colors are solid colors intended for coverage. For many projects, starting with either Opaque White or Black works best as a base followed by Transparent and other color types. Opaque colors work best with larger tip-sized airbrushes operated at higher PSI settings.Opaque Colors have a high pigment load and added filler for opaque coverage out of the bottle. To assist flow and atomization, Opaque Colors may be thinned with 5601 Transparent Base or 4012 High Performance Reducer. Add 4030 Mix Additive to Createx Airbrush Colors for improved spray performance and adhesion on plastic, vinyl and application onto hard-surfaces.
