Comments:	Reflectance spectrum of pure culture of Halobacterium salinarum (DSMZ (https://dsmz.de/) strain ID #22414). Measurements made with Ocean Optics USB2000+ UV/VIS spectrometer (grating #3) with Ocean Optics R400-7 reflectance probe.
		Visual color pink-red. Absorption over 480 - 550 nm due to bacterioruberin and possibly other carotenoids. Strongest increase in reflectance over 560-700 nm."
