The colors are added to the image later, as the data from the various filters are translated into the spectrum of visible light, Pagan explained. The longest wavelengths appear red, while the ...

The blue, which is the shortest wavelength of visible light, bounces back out, meets our eyes, and results in a deep aqua color. Should never walk on any ice alone. The risk of slipping on the ice ...
