About the shape of the hull, seams to me that it isn't exactly perfect, especialy the bow its too thick, Thats the only thing i' ve notice.
About the colors i'll send you fotos by e-mail of the kit. they arenĀ“t very clear but migth help. I found these fotos in the web in some modeler webpage. It is the Trumpeter 1:350 Hornet.
The color inside the hanger is a very light gray, may be white, i'm not sure. However it is used in all U.S. aircraft carriers i've ever seen, but the hanger deck floors i dont know.
