Back in 2007, the U.S. Open once again right down to the wire in front of a big crowd at Oakmont Country Club. That year, it was Angel Cabrera who barely was able to edge Tiger Woods and Jim Furyk by a stroke. Previously, the Open was also held at Oakmont nearly every decade since 1927.
All of the wavelengths present in visible light form colorless white light when they are combined, but can be refracted and dispersed into their individual colors by means of a prism. The colors red, green, and blue are classically considered the primary colors because they are fundamental to human vision. All other colors of the visible light spectrum can be produced by properly adding different combinations of these three colors. Moreover, adding equal amounts of red, green, and blue light produces white light and, therefore, these colors are also often described as the primary additive colors.
The twelve hues of the color wheel are divided into primary colors, secondary colors and tertiary colors. Primary colors: There are three primary colors. They are the hues yellow, blue and red. These three colors are the hues that in theory can be mixed to make all other colors. If you mix the three primary colors, in theory it would produce black. Secondary colors: By mixing two primary hues together you create a secondary color. There are three secondary colors. They are the hues green, violet (purple) and orange. Orange from mixing red and yellow, violet (purple) from blue and red, and green from yellow and blue. Tertiary colors: The third set of hues are known as tertiary or intermediate colors. These hues are made by mixing adjacent primary and secondary hues.
