Raw Sienna Pigment Stick A revolutionary development in painting, R&F Pigment Sticks are oil paint with just enough natural wax added to maintain a solid stick form. They are richly pigmented, with a lipstick soft consistency that gives them the same fluidity, subtlety, and durability as traditional oil colors, with the gestural spontaneity of direct drawing. Luminous, deep golden undertone, excellent for glazing. Top tone is a rich caramel. Beautiful interplay of tones comes through in laying on a stroke of paint.
