Color is perhaps the most important aspect of your visual language and can be the most complex. Color has the potential to engage a viewer more powerfully than any other design element; it can override all other considerations in a design. This most important fact to remember about color is that it is a property of like rather than the object itself. Objects have no color of their own, but rather the ability to reflect certain rays of light which are perceived as a
certain color. As light changes, color changes.

Many scientists throughout history have studied the phenomenon of color. Sir Isaac Newton was the first to discover in 1666, that pure while light could be divided into different wavelengths of color through the use of a prism. By refracting a small beam of sunlight through a prism, he was able to project bands of colors onto a white surface. What he found was a rainbow like spectrum of color in the following order: red, orange, yellow, green, blue and violet.

In doing this, Newton was able to prove unequivocally that color is light and that all of the colors we see in the world around us are contained in sunlight as individual wavelengths.
