Indigo
Organic, Inorganic - My deep, rich Indigo is both organic and inorganic: it is transparent, has an average drying time, demonstrates excellent lightfastness, and possesses high tint power. Artists have yearned for high-quality Indigo for years, but finding and securing an Indigo pigment that met my high standards was essential before I considered making an oil paint colour. I finally found one I like. Nocturne painters will be especially pleased as this Indigo is what they’ve been waiting for! Artists who like painting sultry skies or more conservative painters looking for ways to enhance their greys and shadows should try this Indigo. No. 228 is rich, deep, and dark, with uncompromising quality and consistency. It is delicious, beautiful, and inky.
