These do not necessarily have to be black, but can also appear in a different color, eg red or blue. Dark colors, however, are advantageous for the recognizability of the subject.
  • These mentioned metallic subwavelength structures show an increased light absorption in the visible spectral range, partly due to a resonant light absorption, which leads to a sparklingness of the reflection. A high contrast between the contour area and the subject area or background area is ensured, since the average absorption in the visible wavelength range is always higher than that of mirror-smooth surfaces, such as micromirrors.
