Visual Texture

Starry Night by Vincent Van Gogh is a great example of visual/implied texture. You cannot physically touch what's in the picture because it is flat, but it looks like you can.  The small brush strokes in the sky makes it look very rough.  The blue and yellow combined also gives it a 3D effect. It creates an illusion and does not try to depict the texture of the sky itself. It tricks your mind into believe that there is something you can touch.
