A circle shape that is divided equally in to 12 sections, with each section displaying a different color according to its pigment value. As all colors are created from the three primary colors (red, green and blue), the primary colors are shown forming a triangle within the color wheel. The color wheel shows the relationship between the primary colors, secondary colors, and complementary colors.
I’ve seen photographers say you should get a color wheel and understand the relationship between the primary colors and the secondary, and complementary colors.
The color wheel is designed for decorators to coordinate colors as they are putting together fabrics, paints, wall papers, etc. and make sure all the colors work together.
I don’t see how the color wheel has any value for a photographer because we don’t get to choose the colors that are in our subjects, the subject colors are already determined and we shoot what is there. If it’s a great subject, I’m gonna shoot it regardless if the colors work on a color wheel, so again not sure why photographers talk about the need to learn the colors of a color wheel, because we have no control over the subject color. Unless you want to change it in photoshop.
