Complex inorganic titanate pigments with low dopant levels (i.e., less than about 5%) exhibit coloristic and enhanced infrared (IR) reflectance characteristics that make them useful in formulating colors exhibiting high IR reflectivity. This characteristic is becoming increasingly useful as a way to keep exterior surfaces and articles cooler during exposure to direct sunlight. Achieving this can decrease energy (e.g., cooling/air conditioning) consumption and costs. Low-loaded titanates can boost IR reflectivity by 1 to 10% in selected visual color spaces. Paint compositions containing those low loaded titanate pigments and a method for providing a surface with high infrared reflectance utilizing those pigments are also disclosed.
