Phthalocyanine green has good fastness and durability and it is used in applications similar to those for phthalocyanine blues.
The most widely used red pigments in automotive applications are the quinacridones, due to their good colour and solvent fastness. These vary in shade from scarlet through to violet and maroon. Toluidine and thioindigo reds are also used.
4. Yellows & Oranges
For health & safety reasons, the lead based chrome yellows and oranges have been replaced by the much more expensive flavanthrone yellows, perinone and indo oranges.
5. Transparent Iron Oxides
These stable pigments are extremely useful in formulating gold and bronze metallic or polychromatic enamels.
