That looks to be a 1977 or 1978 Monaco. Assuming the police didn't use a special color mix, you've got a choice of four blues. Your picture isn't the best for color matching, but I'd guess it to be either the Wedgewood Blue or Cadet Blue.
I think it may actually be silver, looking a little blue-grayish because of the lighting and age of the film emulsions.
Regardless, it will be a period Chrysler color as Jan said. Rather than mail-ordering ... you might wait until Saturday to see Scalefinishes' complete line of automotive paints that Jameston Kroon will have on the table at Desert Scale Classic. If he can't hand you the color you need, he'll be able to whip it up and ship it to you as soon as he gets back to Salt Lake City.
And, his prices are usually much better than reasonable ... especially toward the end of the show.

Hey Jonathan, I cleaned this up in Photoshop just auto-adjusting the color...It seemed to take alot of the faded look to the picture out and give a clearer look at the color. When I select the color right from the photo and compair it to the color chart that FMW gave It is really close to the "SILVER CLOUD" or if I pick the sample from the front fender above the marker light I get a match for the "SILVER FROST" (which in the photo is just a tic darker than the door or the fender from the wheel back) color So I would maybe go with one of those 2 that if I was doing it ...I think I would lean towards the "Silver Cloud" myself...Hope that helps
