I have the LT 0 in gray mist, and it is a true gray. But I know what you mean about the color. I have a Ross Rhythm in gray, and when I bought a spare spool for it a few years ago, the spare looks purple instead of gray. It does not match the reel frame at all when I switch lines. I know exactly which one is the spare and which one is the original.
It looks like their anodizing is a bit inconsistent over there.
