Color wheels are essential for artists while they are painting and/or studying color theory. They can be really basic like the one above, or far more interesting and ascetically pleasing to the eye like the rest of the ones I'll include.
Besides being a tool for color study, people will in fact argue that color wheels serve no real purpose. But what what if you got creative with it? Thought outside the box, or in this case, the circle? Well, then it can transform into an art piece itself!
Have you ever made a color wheel?
