Blue thoughts

Mom and me in 1995 at what was then known as The Jake. We had season tickets then so it was a nice confluence of events that the Cleveland baseball team made it to the World Series that year. Can’t afford it now.
Anyway.
This is a picture of a picture but what strikes me is how the color skews toward blue. Admittedly this is a more than 20-year-old photograph but what is it about either the film’s composition or the development process that makes blue the color that survives? Not just this photo, but if you look back on old pix, old advertisements, everything fades except the blue. I’m sure there is chemistry involved too.
Perhaps Kodak has the answers.
