Abstract
A LiDAR reflecting dark colored pigment includes a core layer formed from a reflecting material and a first layer formed from a first absorber material or a first dielectric material extending across the core layer. A second layer formed from a second absorber material different than the third absorber material extends across the first layer and a third layer formed from a third absorber material or a second dielectric material extends across the second layer. The third absorber material is different than the second absorber material. The LiDAR reflecting dark colored pigment reflects less than 10% of incident visible electromagnetic radiation and more than 60% of incident near-IR electromagnetic radiation with wavelengths between and including 850 nm and 950 nm for all incident angles of the visible and near-IR electromagnetic radiation between and including 0° and 45°. A color reflected by the multilayer stack has a lightness in CIELAB color space less than or equal to 40.
