Optical fibers generally are not able to transmit ultraviolet light because the short wavelength light can interact with dopants or impurities in the fibers, resulting in so - called «solarization» damage and extreme losses of beam intensity.
«More specifically, different colors (or wavelengths) of ultraviolet light can affect oxygen and ozone production and destruction in different ways.»
Mice have two types of cones — one that is sensitive to medium - wavelength green light and one that is sensitive to short - wavelength ultraviolet light (UV).

The «colours» are due to differences in the surface temperature of starsw1: hotter stars emit most of their light in the visible blue or ultraviolet regions of the electromagnetic spectrum, whereas cooler stars radiate at longer wavelengths, in the visible red or infrared regions (see Mignone & Barnes, 2011a).
