: ON THE SEMI-NEUTRAL, MARRONE.
or Marrone Lake, was a preparation of madder, of great depth,
transparency, and stability. Working well in water, glazing and drying
in oil, and in every respect a good pigment, it was one of those colours
which gradually--and often, as in this case, unfortunately--become
obsolete, on account of their hues being easily given by admixture of
other pigments. There was likewise a deeper kind, called Purple Black. A
good madder marrone may be produced by adding to brown madder either
rose madder, madder carmine, or Rubens' madder, with a slight portion of
black or blue if required.
