Rouge (ˈruːʒ; meaning "red" in French), also called blush or blusher, is a cosmetic for coloring the cheeks in a variety of shades, or the lips red. It is applied as a powder, cream or liquid. The Ancient Egyptians were known for their creation of cosmetics, particularly their use of rouge. Ancient Egyptian pictographs show men and women wearing lip and cheek rouge. They blended fat with red ochre to create a stain that was red in color. Greek men and women eventually mimicked the look, using crushed mulberries, red beet juice, crushed strawberries, or red amaranth to create a paste. Those who wore makeup were viewed as wealthy and it symbolized status because cosmetics were costly. In China, Rouge was used as early as the Shang Dynasty. It was made from the extracted juice of leaves from red and blue flowers. Some people added bovine pulp and pig pancreas to make the product denser. Women would wear the heavy rouge on their cheeks and lips. In Chinese culture, red symbolizes good luck and happiness to those who wear the color. In Ancient Rome, men and women would create rouge using (red lead) and cinnabar. The mixture was found to have caused cancer, dementia, and eventually death. Other sources for rouge (raw materials) included malachite and antimony In the 16th century in Europe, women and men would use white powder to lighten their faces. Commonly women would add heavy rouge to their cheeks in addition. Studies have strived to research other reasons as to why individuals choose to color their faces in a red tint and what blushing may also signify to others. Blushing, the body's natural reaction to feelings of shame/embarrassment/guilt is often followed with a reddish coloring on one's cheeks on individuals whose bodies react as such. This reaction can be associated with different moral and human tendencies such as pro sociality and commitment to social relationships. Emotions are involuntary and instantaneous reactions, and because of this are pretty reliable.
