- outside1234 7y agoThe short answer is that absorbing a narrow band of energies is more efficient than a wide band. See: http://scienceline.ucsb.edu/getkey.php?key=4979 http://scienceline.ucsb.edu/getkey.php?key=4979
- quote 7y agoBecause other wavelengths were probably already taken. https://en.m.wikipedia.org/wiki/Purple_Earth_hypothesis https://en.m.wikipedia.org/wiki/Purple_Earth_hypothesis (Black is not a wavelength but rather the absence of visible light, e. g. it has all been absorbed)
