ELI5: Explain Like I'm 5

Chromatic circle

Imagine you have a colorful toy and you want to arrange the colors in a circle around it. You start with one color and then move on to the next, eventually making a complete circle. This circle of colors is called a chromatic circle. It helps you understand how colors relate to each other and how they can be combined to make new colors. Some colors are next to each other on the circle and are called "analogous" colors, while others are opposite each other and are called "complementary" colors. By using a chromatic circle, you can choose colors that match well together or create contrasting effects to make your toy look even prettier.
