One Res-N-Gel 37ml and six Permalba oil colors 37ml; Original Permalba White, paynes gray, sap green, French ultramarine blue, cadmium red light, cadmium yellow light. Res-N-Gel is a full strength ready to use, synthetic resin gel. It accelerates drying time. An excellent medium for painting with either brush or palette knife to create a full range of impasto, opaque, translucent glazed effects. Professional Permalba Artist Oil Colors are made from densely concentrated pigments, and formulated with refined linseed and safflower oils which minimize after yellowing and promote maximum film flexibility. With the exclusion of the iridescent colors which are not yet rated, the entire Permalba is rated as ASTM Lightfastness I. Traditional pigments with low lightfastness have been replaced with contemporary alternatives, giving the artist the same traditional hues so richly prized but with superior color retention.
