Abstract: A workpiece composed of acrylic material can be modified to produce a highly visual and aesthetic prismatic effect in which white light entering the workpiece can exit the workpiece in separate colors and sets. By applying dichroic paint and primer to precision cuts made into one of the planar surfaces of the workpiece, preferably filling in the spaces with a resin epoxy and then preferably sanding the surface, many more colors can be generated by the white light exiting the workpiece.

Abstract: A guitar body of a guitar composed of acrylic material can be modified to produce a highly visual and aesthetic prismatic effect in which white light entering the front of the guitar body can be seen as many separate colors. By applying dichroic paint and primer to precision cuts made into the interior cavity of the acrylic base, colors can be generated by the white light exiting the front of the guitar body. Further, the guitar body may be comprised of different materials for its filler core (forming a sandwich of tonal wood and foam) which cause the guitar to be lightweight, while simultaneously enhancing the sound quality of the guitar.
