Hi there, I have to agree with what was said up the top of the page about different lighting giving different variants of blue.
I myself have gone for a spray paint (rattle can) Vauxhall regatta blue,and is the nearest I have found to the blue in other photos and the game footage.
I would upload some photos but currently on iPhone and not sure how and if its possible to upload.
Also what techniques have people been using for the dirt scuff look.. Matt or gloss.. Hand painted or airbrush.. Any feedback is greatly appreciated.
Thanks KNAWJK
