Modern organic pigments known as Titanium White. At Regina's watercolor, we have fun naming colors after what they look like. All pigments and ox gall used are sourced from AP certified manufacturers. Honey, arabic gum and clove oil used in mulling these handmade paints are of the finest quality (food and therapeutic grade). The final product is non-toxic, transparent, lightfast (levels 1-2), artist quality and inter-mixable. Made in the USA.
