No, I’m not talking about brain tissues. The heading “gray matter” refers to the palette of colors that was used to create these three digital abstractions. At first glance, the colors (hues) in this palette don’t seem particularly varied.
On closer inspection of these “grays” we see that there are many variants of “warm” hues from pinks and oranges to subtle greens. Using the blending modes in Procreate app for iPad, I was able to intensify and, in some cases mix these colors to achieve the finished results below. The blending modes, which I have mentioned in previous posts, allow for changes to hue, transparency and intensity of colors that are placed on layers. When the upper layer has a blending mode applied to it, the layers below are affected by that change. To make the final compositions more interesting, I applied a canvas texture to the central objects in each of the three designs.
