1. A coating composition comprising:
- (a) a film-forming resin;
(b) a colored and/or opaque infrared reflective pigment; and
(c) an infrared transparent pigment;
wherein the coating composition, when formed into a cured coating, exhibits;
(1) a total solar reflectance of at least 15% as measured in accordance with ASTM E 903-96; and
(2) an angle dependent color change of no more than 5 Δ
E units when compared to the color of a control coating.
