Black IR-reflective or transmissive pigments from which LiDAR-responsive black coatings can be formed, wherein the pigments exhibit similar blackness M to non-IR-reflective carbon black y Values. The CuO particles exhibit small crystallites with a (−111) / (111) reflection intensity ratio of less than 18 nm and less than 1.2. The method of forming the CuO particles includes precipitating CuCO3 or CuCO3 / Cu(OH)2 using an alkaline carbonate as a precipitant and calcining the precipitate at about 300 °C to about 400 °C.
