Red

March 1, 2008, Taiwan.

 
Red signifies danger, anger, passion, aggression, evil, guilt, sin, love, and even happiness.
Red makes you hungry, represents blood, symbolizes courage and sacrifice, and catches your attention.
Red signifies prosperity, but also death. Red is purity, but also wrath.

Reds range from 630-740nm, the longest wavelengths in the visible spectrum.
Red varies from pink, salmon and carmine to ruby, brick and maroon.

The nasty man and letter-eating postbox look the way they do not just because of the way they are shaped, but also because they are painted red.
