Visual Art students were given an assignment to create a Color Wheel or Spectrum using paint store color chips samples. They could include illustrations, paper cuts, etc. We also looked at a the very creative and popular Sherman Williams ad campaigns using color paint chips.
Once the colors are put in their "wheel" students always comment....How pretty or cool these are!". Why? Because visually they are perfect....just like the rainbow!
What is the purpose of constructing a color wheel? Simply put, to set in your mind the structure of color and how each is made. The three primary hues -- yellow, red, and blue -- are the basic building blocks of color. All other colors are derived from these three. The three secondary hues -- orange, violet, an green -- made of primary colors. And then the six tertiary hues -- yellow-orange, red-orange, red-violet, blue-violet, blue-green, and yellow-green. The color wheel has a total of twelve hues, arranged like the numbers on the face of a clock.
