Description: Consistent color for an economic price. The first synthetic color of the industrial revolution, this enigmatic blue can create a large range of tints from one tube with no mixing. A rich blue with a green undertone, it was popular among Japansese woodblock artists for seascapes. It is the same blue used in blueprints.
