Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Titanium dioxide, often referred to as TiO2, exists in two primary forms rutile and anatase. Rutile TiO2 is renowned for its exceptional optical properties and higher refractive index, making it the preferred choice for applications requiring maximum brightness and durability. This form of titanium dioxide is characterized by its dense particle structure, providing superior weatherability and resistance to discoloration, essential traits for products exposed to the elements.
