Oil Paint is the most versatile artistic medium. It can be applied in thin transparent glazes or thick opaque coats, with a wide range of possibilities in between. It is easy to mix a wide range of colors, tones and chromas with oil paint and it is possible to work in multiple layers; once the previous layer dries. My favorite oil paint is Old Holland due to its intense pigmentation and the way it dries in to "flesh". Old Holland Oil Paint is VERY EXPENSIVE though. The two best options after Old Holland are Gamblin and Rembrant Oil Colors.
A "staple" in all of my artworks is Illustration and Paint Markers. I like to use the illustration markers as a substitute for doing an underpainting, when creating a painting....but the Prismacolor and Ad Markers are great on their own. Click "MORE" to see me do a demonstration.
