also layering can change the texture of a look. for example, if you use a matte shadow under a sheer one, say a frost, you define/smoke under what color you put over it, it is just softened w/ the lighter tone.
or, if u use a cream colored base, you'll have a shiner texture, more pearl-y finish, as opposed to say a paint or shadestick, which tend to be a more powdery finish.
hope that helps!
