Abstract: A portable apparatus for visualizing or practicing a paint color, finish, technique, or texture includes a substrate having a primed first surface and a second surface having means for securing the substrate to a mounting surface, such as a wall. A method for visualizing and practicing a paint color, finish, technique, or texture includes the steps of (a) applying a paint color, finish, technique, or texture to a first surface of the substrate; (b) textually identifying onto the substrate the paint color, finish, technique, or texture applied thereto; (c) securing the substrate to a first portion of the mounting surface; (d) removing the substrate from the mounting surface; and (e) securing the substrate to a second portion of the mounting surface.
