Fear of the dark

Fear of the dark is a common fear or phobia among toddlers, children and, to a varying degree, adults. A fear of the dark does not always concern darkness itself; it can also be a fear of possible or imagined dangers concealed by darkness. Most toddlers and children outgrow it, but this fear persists for some as a phobia and anxiety. When waking up or sleeping, these fears may intertwine with sighting sleep paralysis demons in some people. Some degree of fear of the dark is natural, especially as a phase of child development. Most observers report that fear of the dark rarely appears before the age of two years and roughly peaks around the development stage of four years of age. When fear of the dark reaches a degree that is severe enough to be considered pathological, it is sometimes called scotophobia, or lygophobia.

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
