The first one (Snapper Rocks Blue) is in the spreadsheet already, but it's the old version with same values for base and flake, maybe worth a look?
I'm not sure if Jaguar's British Racing Green has stayed the same over the years. The version I'm requesting is the one found in the Jaguar XK8 and XK, which is more "green", yet metallic, unlike the classic, which is gloss. The F-Type's version, which is in the game, seems to be closer to teal, though it could just be the lighting in the photos. Biggest reason is to have a fun color to paint old Morris and Triumph cars in.
Deep Blue Pearl was made by
@MadaraxUchiha but he said he wasn't finding the values he used, so it'd be best to let him handle it instead, as he was the one who originally took the request.
This list had Viola Parsifae but you made that one already.
If I'm not mistaken, somewhere in this thread there's a request for Viola Hong Kong (Ferrari), which no one took. It's another interesting color to recreate.
P.S.: If you couldn't tell it, I love blue.
