What kind of paint did hokusai use?

Hokusai primarily used water-based pigments known as ukiyo-e paints for his woodblock prints and paintings. These pigments were made from natural materials, including minerals and plant extracts, which were often mixed with a binding agent like rice paste. Additionally, he utilized ink made from soot and other organic substances for his detailed brushwork. Hokusai's mastery of color and technique contributed significantly to the vibrancy and depth of his artwork.
