Staining colors

Staining colors are man-made dye-based pigments that stain the paper surface making it difficult to lift and return to the white of the paper. In general they are known for greater permanence and the hue is more intense, depending on the manufactor some brands stain more then others. If you happen to accenditally drop a little on your painting  if you catch it right away most times you can lift the spot of color out. If needed add drop of water on the spot then "blot" do not wipe.
