White and Light Green:
As I mentioned above, you have the option of using a piece of 1' x 3' lumber for the installation or building a frame to support the cabinets (I have included a picture of a sample frame below). This can be made out of 2' x 4's and should be tall enough to support the bottom of your wall cabinets. If you plan on installing more than one kitchen, then I would suggest the frame, but a piece of lumber will do just fine if this is a one time event. In either case, you will need another set of hands to help with the installation.
Decorative supports, aprons, and corbels are great extra features to add to cabinets. They are not standard on most cabinets, but are a great project to add on to the kitchen after installation of the new cabinet. Decorative supports put an artful emphasis on upper cabinets. The supports were originally designed to help support cabinets, but now they only serve as decor.
