The middle of each color, where it was most vibrant, is marked with a letter. It started with “D” and ran the whole way around to C. Newton compared his color wheel to a run of musical notes. Newton’s color wheel, however, looks a little different than the ones you or I might be used to. Instead of the color line or rainbow that most of us are probably familiar with, Newton instead used a color wheel to represent his version of the color spectrum. Because the colors didn’t seem to be coming from anything and were inherent to the light itself, Newton named them “spectra” (Latin for “spirits”) and the whole arrangement a spectrum. It’s from this original reading of the color spectrum that the acronym “Roy G. So Newton used a screen to separate out a single color from the rest and then passed it through another prism to show that the prism itself wasn’t the cause of the other colors.Īs part of his experiments, Newton found that there were seven colors on the color spectrum: red, orange, yellow, green, blue, indigo and violet. But more experimentation was needed to reach a concrete conclusion. This showed that white light could be broken down into its component colors. Instead of looking to see if phenomena had things in common and using that as the basis for comparison, Newton looked for the differences.įirst, he passed white light through a prism. Where Bacon used the method of agreement to prove his experiments, Newton used the method of difference. Four centuries later, in the 17th century, Isaac Newton would continue Bacon’s experiments. By passing light through a variety of transparent globes or prisms, Bacon was able to infer that this produced a rainbow of color, though the method of producing just one type of color had yet to be discovered. The first discoveries in the science of color were made by the English scholar Roger Bacon in the 13th century. In this post, we’re going to take a slight step back from that and talk about the history of color, how we actually see color and then a little bit about each color spectrum that a graphic artist might use: CMYK, RGB and PMS (Pantone Matching System). One of the biggest elements of good design is color – specifically how best to use it to draw audience attention. Last month, as part of our series on design, we talked about the seven elements of good design.
