M Graham CityScape 5 Color Watercolor SetSet contains 15ml tubes of: Sepia Hansa Yellow Deep Burnt Sienna Paynes Gray Pyrrol Red. Why Honey? As an essential ingredient in the binding medium, honey contributes to moistness for smooth, easily controlled applications, increased pigment concentrations, and freedom from over reliance on preservatives. Because of the honey medium, M Graham watercolor resists hardening on the palette, or in the tube. It dilutes easily, often after months of disuse.
