A multi-component pigment slurry which comprises at least 50% solids. The slurry is formulated to be admixed into paint and coating compositions to promote TiO.sub.2 extension. The slurry includes a structured pigment, a coarse particle size pigment, and a fine particle size pigment. The structured pigment comprises about 20% to about 55% of the slurry by dry weight and has a median particle size diameter of about 0.7.mu. to about 6.0.mu.. The coarse particle size pigment preferably comprises about 20% to about 60% by weight of the slurry and has a median particle size diameter of about 3.0.mu. to about 10.0.mu.. The fine particle size pigment preferably comprises up to about 50% by dry weight of the slurry and has a median particle size diameter of about 0.2.mu. to about 1.0.mu..
