The field of design I am hoping to go into is product design, and one of the kinds of products I hope to be able to design is furniture.  This picture shows a kid's bunk-bed design by Zalf. Its yellow color sets it apart from the rest of the room and shows that it is spatially grouped together, although the adjoining desk is physically separate from the bed.  The shape and size of the bed make it easy to discern that it is the dominant feature in the collection; that it is the main focus and the other things that go along with it are accessories.  The way the desk is oriented to the bed (it's facing it) shows the relationship between both pieces of furniture (showing they are together).  This set is very simplistic and has nice, clean edges.  Overall, the dominating element is the color- it pops out at the viewer first, and manages to hold the viewer's attention throughout the time they are looking at the piece.
