A large white background with bright colors used to depict the molecule itself. As usual, I "embossed" my name in the lower right corner. The final mosaic was 45" square (144 x 144 studs). I have not seen the mosaic in its final placement, I simply shipped it to the company and they assured me that it would be installed to their liking.
Below and a few pictures that show the progress of the build as it lay on my floor.
