Yes, when I first started to do this project I wasn't working at the airport (YYC), I did lots of image searches and what you see in the photos is all shades, ranging from a medium or almost pale blue to a blue that's almost a black/blue. But Canadian North have a hanger/charter terminal at YYC and during my time there, had the opportunity to get very close to their aircraft due to the nature of my job. Close being as in less than 50ft away. The shade when you can see it that close is what I'm trying to achieve, it has a chrome finish to the blue which is more like the Humbrol French Blue with a very shiny finish. I actually have the exact paint code for it that the maintenance manager sent me after I had written to Canadian North to see if they had a colour chip I could use to get some paint mixed. Using the code would be the correct way to go but there was a problem, I could only buy it in 5gal pails, with a minimum of a pallet of pails
(not sure how many pails that would be). Even with my plan on building a couple of 1/72 737s that they operated to go with this build, I'd be lucky if I used a quarter of a pint for all three
Here's another photo of a real one
