In a pair of blog posts, the online design magazine Imprint offers an illustrated history of the color wheel. From enlightenment thinkers such as Jacob Christian Schäffer and Moses Harris, to German author Goethe, mathematician Tobias Mayer, and painter Albert Henry Munsell, these articles trace the very colorful history of human efforts to categorize colors and theorize on the relationships between them. The world of science and art may by now have moved on to more systemized – and scientifically rigorous – categorization systems, but color wheels are by no means obsolete, the author concludes:
However inadequate, scientifically speaking, it is to describe the color-spectrum using a wheel-shaped model, there’s an irresistible fitness about marrying circles with color. As a geometric figure, circles possess a certain strength, a self-contained quality in which a smooth, unperturbed body can be imagined to hold an entire universe. Sometimes the pod will crack, spilling its contents with rampant energy, or maybe the circle holds indefinitely. For an entity as slippery and ubiquitous as color, only a circle can be imagined as a perfect enough shape to contain all of it.
And indeed, if you have an eye for it, color wheels can be found anywhere.
