Misc. Information:

  • all cadmiums are compatable

  • Mixing Browns: There is no need to buy browns. you can create similar colors by mixing Phthalo Blue with Quinacridone Burnt Orange.

  • Protecting the white of the paper

    • In transparent watercolor, keeping the white of the paper pristine is a major goal. Because white paints are rarely used, sparing the white of the paper and using very light-value colors are the way both white and light are best expressed.

      • avoid the white/light areas by painting around them

      • using artists tape for straight lines

      • using frisket, masking fluid or wax resist to protect any shape you want

  • black - the banned color

    • avoid muddy darks. Clear, transparent, non-muddy darks are essential to a good painting. If you need to go darker, use colors that are the darkest values of their particular hue or color.
