Advance Catalysis, Volume 186, 3-12 Solar energy conversion Some ruthenium complexes absorb light throughout the visible spectrum and are being actively researched for solar energy technologies.
A major challenge for the researchers was working in the blue range, which has the smallest wavelength in the visible spectrum and scatters more than other colors because it travels as shorter, smaller waves.
An additional difficulty is that red dwarfs radiate most of their electromagnetic energy as infrared light, whereas plants on Earth capture most of their energy from the visible spectrum.
Charles Q. Choi from LiveScience.com further explains that unlike the Hulk, gamma rays are not green; existing as they do beyond the visible spectrum, gamma rays have no color at all that we can describe.
Animal color vision seeAlso Many species can see light within frequencies outside the human "visible spectrum".
At short wavelengths (the visible spectrum) the atmosphere scatters light, thus slightly increasing the star's diameter.
