Was admiring these wild red flowers that a co-worker brought us today and wondered why does red signify love! Why not blue, white, yellow, pink, purple, and so on? Loads of beautiful colors in the world so why was red the chosen one?
Red also denotes blood, a warning or an error message in documentation, or is used as a sign of failing a test or exam when teachers use red pens to differentiate the grades. It also denotes the traffic signal or those signs on the highway signifying some danger ahead. There are also so many idioms or phrases associated with the color red such as "seeing red" or "red tape" or "receive a red card", so wonder why is red used in the context of love?
