I have a '76 GMC with the original factory color scheme that looks exactly like the picture in your first post. The SPID reports code 23L. Just as you mention, I have often thought that the two-tone scheme would look better with the white accent color, offering more contrast. However the two shades of blue (tone on tone my wife calls it) does have some class. Since I have two blue '76 GMCs I am solving this dilemma by going high contrast with one, and leaving the other with the two-tone blue. Regardless, your '75 looks very sharp - nice legacy for your family.
