>This article is about the color. For other uses, see Pink (disambiguation). Pink is a color made by mixing red and white and sometimes described as being a light red, but it is more accurately a bright undersaturated red. There are many different shades of this color. "Pink" was not a color word known to Shakespeare: it was invented in the 17th century to describe the light red flowers of pinks, flowering plants in the genus Dianthus, possibly named from the "pinked" edges of their petals appearing to have been cut with pinking shears.

>For other uses, see Smile (disambiguation). In physiology, a smile is a facial expression formed by flexing muscles most notably near both ends of the mouth, but also around the eyes. Among humans, it is customarily an expression of pleasure or amusement, but can also be an involuntary expression of anxiety. There is much evidence that smiling is a normal reaction to certain stimuli and occurs regardless of culture. Many studies indicate that smiling is an innate reaction, as children blind from birth smile; however feral children generally do not smile, perhaps lending evidence to the contrary. Among animals, the exposure of teeth, which may bear a resemblance to a smile, are often used as a threat - known as a snarl - or a sign of submission. See more at Wikipedia.org...
