A fisherman in the sunset is waiting to catch fish, in the time you want to observe the nature. Now all is Blue. Light is the part of the electromagnetic radiation that we can see with your eyes. The light spectrum for the blue here I would estimate at 450 nm. The shorter the wavelength, the higher the frequency and the higher the photon energy. Blue light has more photon energy than red.
By the way, here I can show you the original red version Fisher In Red.
