Red flowers and Blue flowers

Red flowers are of so many different shades that it is only possible to give a general idea of colors to be used in painting them.

For deep red flowers use madder lake, ivory black, yellow ochre, vermilion and white, adding burnt sienna or Indian red in the deeper shadows. The vermilion and yellow ochre may be omitted in cooler tones, and a little cobalt added if necessary.

Those of bright scarlet are painted with vermilion, madder lake, yellow ochre, and white qualified by a very little ivory black.More vermilion and less madder lake are used according to the tone of red to be produced. In shading use raw umber, light red, madder lake and ivory black, adding a little cobalt if necessary.

Blue flowers may be painted with Antwerp blue or permanent blue, according to the tone desired. The Antwerp blue is combined with white, light cadmium, raw umber, madder lake, and ivory black, with burnt sienna added to the other colors of the shadows. This produces a warm greenish blue.

The cool purplish blues are made with permanent blue or cobalt, mixed with white, a little raw umber and ivory black, adding to these colors madder lake or light red in the shadows.
