I decided to use Texture for this one. It has several different types of texture.
Texture translates the quality of a surface, representing its look and feel. The qualities of texture may range from soft to hard, smooth to rough, wet to dry. The look (or implied texture) does not have to match the feel (the tactile or real texture).
