Hi PaulThe BR blue values that I've used for my reskins are:
R 0.0
G 67.0
B 76.0
html 00434c
This version is in use for the Class 25, 44, 45, 46 locos, class 107, 116, 117, 121 DMUs and Mk2C and Mk3A coaches. It would be nice to see these locos match that.

Those RGB values are where I started, but PBR textures look somewhat different and I'm working through how best to make the textures sit well with non-PBR stock. I've spent a few hours now experimenting and I think I'm just about happy with this:
This uses the RGB values you've specified, but with an AO bake overlay in my image editor (Corel Photo-paint) set to subtract 100%.
