Createx Airbrush Transparent Colors Vibrant colors which do not have fillers for opacity. Transparent Colors most often work best over a light surface or base color such as Opaque White. Transparent Colors have a high pigment load for semi-opaque coverage out of the bottle and may be reduced with 5601 Transparent Base or 4012 High Performance Reducer to increase transparency and assist flow & atomization with smaller airbrush tip-sizes. Add 4030 Mix Additive to Createx Airbrush Colors for improved spray performance and adhesion on plastic, vinyl and application onto hard-surfaces.
