Ultramarine Blue (PB29) 15ml Tube, DANIEL SMITH Extra Fine WatercolorUltramarine Blue plots cooler and bluer than the more saturated French Ultramarine. Temperature aside, both blues have equal permanence, lightfastness and semi-transparency.
Ultramarine Blue is slightly less granular in concentrated washes. For less saturation, sedimentation and cost, use Ultramarine Blue straight, for vibrant crayon-like color or mixed with a cool red for dark, effective neutrals.
