1. A composite material comprising:
a black pigment; and
a textile material, wherein
the black pigment comprises CuO comprising a near unity ratio of (−111)/(111) crystal facets and a crystal size around 100 Å for the (−111) plane,
the composite material has a reflectivity toward a band of near infrared electromagnetic radiation within a wavelength from 800 nm to 2500 nm of greater than or equal to 12%, and
the composite material has a reflectivity toward visible light having a wavelength from 350 nm to 750 nm of less than or equal to 10%.
