The American flag was adopted in 1777 and originally called The Stars and Stripes. Over the years, tradition has given meaning to the colors. 

RED is for hardiness and valour
WHITE is for purity and innocence
BLUE is for vigilance, perseverance and justice

The US Code declares that a flag displayed horizontally or vertically against a wall should show the Union (the blue portion) at the top and to the viewers left.
