Not sure what an LS 300 is, but Steve's tip above is a good one-
I went to the local Chrysler dealer, and there are indeed cars
there in "deep sapphire blue pearl coat"- I saw several 300Ms
and
Sebrings in the color (and also a PT Cruiser in a similar, but
slightly different, "patriot blue" or somesuch).
Unfortunately, it was very foggy out without much sunlight...I
did see a Sebring in the showroom under fluorescent light which
looked very much like the RT10 at VOI6 color - the cars outside looked
almost black...
