What is the significance of the number seven in color theory?

The number seven holds a special place in color theory due to its historical and symbolic significance. In traditional Western color theory, the visible spectrum is often divided into seven colors: red, orange, yellow, green, blue, indigo, and violet. These colors are famously associated with Isaac Newton, who first categorized them in the 17th century. Understanding this division helps in grasping the basics of color perception and its impact on art and design.
