Lukas Berlin is a water mixable oil colour made from linseed and sunflower oil. It offers the same sensation as a traditional oil colour, and removes the need for solvent-based medium to dilute it. The well balanced range of 40 vibrant colours can be thinned, mixed, and washed using water, and as such is ideal for use indoors and in a classroom environment. Excellent lightfastness, opacity, and brilliance. Surface-dry between 5 and 7 days, with no colour shift from wet to dry.
