I was just thinking if all the creators could aggree on one br blue colour as most of the br blue locos are a diffrent tone.
P.S. this was just a thought
It is annoying I admit, but these are all colours used on our railways http://www.3dtrains.com/guides/msts_colors/railroad_colors_uk_index.shtml
Remember that paint will fade on loco's that are outside in all weathers, so you
will naturally get a spread of shades of the same original colour.
Also I think it may depend on how each creator has the "Gamma" set on their machine.
