Hi Eth,
I'm not too familiar with Mr Color, and I don't think those paints favour too kindly in paint conversions/charts. Here is 2 links for you that may help:

Not having the kit I don't know, looking at a few pictures it looks more blue than grey toned. Isn't it mainly an air force Asset? They use blues a lot in their paint stocks for aircraft so maybe this is where the scheme comes from? Am sure some of the more knowledgeable guys on here will be able to confirm for you.
Best of luck with it and be sure to give as a look at your build!
Cheers
Glen
