Take both an emulsion ground or Absorbent Ground/Watercolor Ground and mix in a dry pigment to bring the end result to a colored ground without effecting the binder and the grounds working qualities. The results will be the same if left out, except the surface will now be toned. Example: Raw Umber as the dry pigment for portraiture or Cadmium Red Light for landscapes. The acrylic based grounds (for watercolor) have titanium white in them and will lighted/reduce intensity for the final-colored ground. The emulsion (for oil painting) will have marble dust and better retain the original dry pigment color/intensity.
