Abstract
A paint system is provided that includes a foundation base component combined with a tinted, opaque top coat component and that hides any colors on all types of substrates and maintains the brightness and cleanness for all colors. The foundation base component is a tintable color base containing at least one organic synthetic pigment at an amount of at least twice as much as the amount of organic synthetic pigment in the top coat component. The tintable foundation base component has a volume ratio of organic pigments to inorganic pigments of at least about 0.5 and a volume ratio of organic pigment to polymer binder of at least about 0.1. The volume ratio of organic pigment to polymer binder in the top coat component is less than about 10.1 with at least about 80% by volume of pigments being synthetic organic pigments.
