Help! Color ID

I’m new(er) to vintage coach and I have a vintage black 9966 with silver hardware that I love. I was at Plato’s today and found a blue one with brass hardware in pretty good condition! Getting it home and doing some more research, I can’t find this style (9966) anywhere online in this blue color. So now I’m calling in the experts…does anyone have more info on this style/color combo (year it was made, etc.)? What is this color called? Thanks in advance!
