  Not only is Dr. No in color, but when you see the new restored DVD and 
Blu-Ray, it's gorgeous color.  I was really struck by its color in a 
recent viewing, the early part of the film especially evoked an old 
world style where filmmakers  had technicolor consultants on hand to 
make sure every scene had a full and pleasing complement of colors.
