The Meaning of the Designations “C.P.” and “CC”

    • Hi Bob!…It is hard to find an orange red that has the punch of Cad Red Light,…but the Pyrrole reds and oranges are very nice.

    • Hello Kim,

      The “C.P.” designation does not have anything to do with being less toxic or less absorbed or less accumulating in the body if absorbed. This grade of cadmium contains more cadmium than the lesser grades, so in a sense, one could say the lesser grades are less toxic. Of course, no amount of cadmium ingested or absorbed through inhalation would be a good thing.

      Cadmium pigments are not believed to transport across healthy, unbroken skin. The main concerns are ingesting or inhalation of the dry pigment or sanding dust. One should always protect oneself from accidentally getting the paint, dry pigments or sanding dusts into ones mouth, nose, lungs or into any abraded skin or cuts. If getting paint on your hands, one should not be touching food to eliminate any accidental ingestion. Some artists prefer to wear gloves to eliminate this potential.

  1. Wonderful article! Thank you for explaining. Some of the cadmium colors are so beautiful that I can’t live without them. They are bright and radiant.
