Michael Harding says of his paints:

"There are no fillers or extenders or driers within these oil colours"

"I formulated this range to the highest standards possible, reintroducing artists' oil paints with the original colour intensities that artists would have experienced prior to the 1840s, which was when the invention of the collapsible tube led to mass production and gradual dilution of quality."

"The majority of artists who try my paints for the first time are shocked by the discovery that they had previously been painting with muted colours."
