Warm Additive 1 oz. All airbrush colours are not the same. Com-Art is considered to be one of the finest and most versatile professional airbrush colours in the world. Because of a common hydro-carbon base binder, Com-Art transparent and opaque colours can be used together without bleeding between colours. This non-toxic, ready to use paint is specifically formulated for use with an airbrush and never needs to be filtered or strained. Com-Art colours are heavily pigmented and light fast, allowing for accurate 4 colour separations. They provide superior atomization, smooth spraying, and they dry instantly.
