Skins for the MA have to be realistic replicas of real life WW2 vehicles so the colours used are researched to be as accurate as possible, not to match the MA terrain. Having said that there is a lot of debate in military and modelling about the colour of the paint actually used on the T-34. The factory green used was known as "4BO" and depending on the source this could have been from anything from a bright acid green to a dark dull green. The paint may have darkened with age or varied between paint factories, which perhaps accounts for the confusion. I have found five different 4BOs on the web so far, so I have a bit of wiggle room regarding the final colour.
I can't do a DR7 skin for the MA as it wouldn't comply with HTC's rules for skin submissions. However I could do a skin for something like a DR7 memorial event, where it would be added to the event terrain as the default skin.
