Provided are a black pigment composition for heat-shielding coatings that has superior infrared radiation transmittance, approximates the hue of chromium-based black coatings not only in a dark color, but also in a light color as well and therefore facilitates hue adjustment when mixed with a chromatic coating, has superior weather resistance and is also advantageous in terms of cost, as well as a heat-shielding coating that uses the same, and a shading method. The black pigment composition for heat-shielding coatings contains, at least, a phthalocyanine blue pigment as a first pigment and a phthalocyanine green pigment as a second pigment, and further contains at least one other chromatic pigment, wherein, regarding the amounts in parts by weight of the phthalocyanine blue pigment as Mb, of the phthalocyanine green pigment as Mg, and of the total of the at least one other chromatic pigment as Mn, 1.5 < Mg/Mb < 4.0, and 2 < Mb < 20 17 <Mg < 40 45 < Mn < 63, are established. |
