I was given a really nice kit at a club white elephent exchange. It is the Hasagawa F-16 block 60. Now the colors on the box art and from pictures from Qoogle Images shows what to me seem to be slightly blue-green tint to the grays. Hasagawa calls for Humbrel dark, medium, and light gray. Is the slight blue-green a matter of my imagination, or is there a slight tint to the gray?
