That could make sense.
Or maybe RAM has nothing to do with the actual colour. I don't think there is any intrinsic property in RAM that says it must be black or grey. I think they could probably make a compound which is bright pink ad is just as effective in absorbing radar.
So what I'm saying is that the change in colour is probably only just that: a change in colour. Why whet there is addition or change in RAM is something we cannot extrapolate with the little information we have
They don't. RAM is used on large constructions like large bridges so not to disrupt navigational view. An example would be Seto Ohashi crossing between Honshu and Shikoku.
