In one particular piece of official art for Super Mario Odyssey, Mario’s hair is rendered in great detail. Zooming in to the part above his ear, we can see what appears to be a single gray hair. This seems to be deliberate, as analysis of the image reveals that this is not a transparency issue, but that the hair is indeed colored a lighter color than the rest. Due the image being released in a lossless format by Nintendo, this also could not be a compression artifact.
