I am not trying to open a can of worms here, but, our models are supposed to be scale representations of the real thing. If it wasn't an important issue to a lot of modelers there wouldn't all the after market stuff to correct inaccuracies. There wouldn't be debates on forums, especially WWI forums, over correct colors of markings or lozenge fabric colors. I know the key thing is to enjoy the hobby, whether you build out of the box and don't worry about seams or you add every after market detail you can to your model that you can find. Reviewers will always discuss the accuracy of the kit. If your interested about that why not the correct colors. i am tired of hearing the line that the paint batches were different. Yes the were but not by great amounts of difference. You only notice the difference when you to different batches side by side.
I have been using Humbrol paints for years and when I use RLM 70 & 71 the contrast isn't any greater than the real 1 to 1 plane. So, I disagree with you there Gil.
We add details to models that wouldn't be seen at real distances of the 1 to 1 object, but we know they are supposed to be there, so our brain tells us it doesn't look right if we can't see it. When we look into a models cockpit, lets say a 1/72, and we don't see the instruments, switches and throttles, etc. it looks empty.
I will end this on the note that I personally want my models to be accurate and I don't mean every little detail added, I mean the detail that is there, the shape and colors. A friend of mine built his models without filling the seams and just followed what was in the instructions for painting. I had no problems with his models. I say to each his own.
