A character or person depicted has grey colored hair.
Due to the subjective nature of color judgment and other factors (such as differences in color displayed on monitors) there is potential overlap between this tag and the blue hair, aqua hair, and purple hair tags, generally in the lighter shades of those colors. Grey is also often used to shade white hair. It is a good idea to compare the hair in question to how other white things, namely white clothes, are shaded. If the shading on the hair resembles how white clothing is shaded, it is likely white, and not grey.
