Try NORMA Blue for new creative possibilities in your oil painting. Schmincke NORMA Blue is a range of 48 highly pigmented, water-mixable oil colours that are environmentally conscious, vegan, and allergy-friendly. They do not contain cobalt, cadmium, or zinc oxide pigments, making them eco-friendly, low-odour, with a buttery-paste consistency. Perfect for indoor painting and classroom use, they clean up easily with water and are compatible with traditional oil colours. PLEASE NOTE: These are still oil colours and as such you're surface will need to be sized or primed to protect it from being damaged by the oil content.
