If the artist does not wish to use water, Duo can be used as a traditional oil color. The paint is water soluble, but the oil is identical to that used in Holbein Artist Oil Color.There is no water in the product, only a surfactant which covers the pigment and oil, making both water sensitive or soluble. The paint blends with other oil colors and oil mediums, though water solubility will be lost if traditional oils or oil mediums exceed 30% of the mixture.
