Oh my goodness ! What a spectacular result you ended up with... It was worth all of the time and effort you spent on the cutting and trimming work.
This has to be the best decal work I have ever seen. If I didn't know better, I would have thought these were sprayed on using paint... It's THAT good ! 🙂

You are absolutely correct about looking at black and white photos and trying to make an educated guess. I have had this picture stored on my computer for a long time now.
It could have been colorized, but I'm not sure if it was or not. I found it before it became popular to colorize pictures, but that doesn't mean it has not been... you just never really know.
I also have had this black and white photo of the same plane on the ground. Click on the photo and it should make it larger than just how it looks in the post. You can see the details a little better when you do.
To me the #15 on the fuselage hinomaru looks to be a bit darker in shade than the white ring surrounding the insignia. Granted it isn't as dark as the numbers on the vertical fin and rudder, but that could be due to the angle of the sun too. It could also be my computer monitor.
As a second option, take a closer look at the last plane in the group. It has a number that looks like a 38 (or it could be 88), and it is also inside the fuselage Hinomaru. It definitely looks darker than the white surround. It is just visible behind the rudder of second plane, which is tail number 343-37.
It's really hard to know with 100 percent certainty, and it's probably also something we will never know for sure.
To be perfectly honest, with the markings looking as nice as they do right now... I wouldn't change a thing.
