QoR is the only watercolor made with Aquazol, a revolutionary new binder delivering color with superior clarity and intensity while preserving all the subtlety and beauty you expect from fine watercolors. QoR unlocks the potential that has been trapped within traditional paints for centuries. Used in combination with QoR Mediums and Grounds artists can increase gloss, improve flow or wetting, and work beyond paper on different textured surfaces for greater control and creativity.
