They're all beautiful, and change under different light..
The grey was kind of unique but everyone and their brother is making cars in that color these days. Not that I want to stand out, but it's becoming pretty common. The (US) blue is gorgeous, as is the red, but they do stand out a bit and I personally don't think the black chrome goes all that well. The guy here who has blacked out a lot of his red car, his looks really good - but not subtle. For me, that matters.
Black is the best looking for me, as it hides the trim and lines and panel gaps - but I'll never own another black car. I've said it before. I might say it again. They look brilliant when perfect, but get less than perfect so easily.
Pantera is close to black but far enough away to hide those imperfections, and has a stunning gold-tinged flake that looks absolutely amazing under the right light. The shade is close to that of the black chrome, so that looks more subtle, more muted - which is my preference.
That said, the snow white pearl has the same flake and looks amazing under the right light, but also highlights the "garnish" trim (that's actually what they call the parts" - not usually my thing, but I think it looks more elegant, refined, than other colors.
I'm going white. And <s>if</s>/when I do choose to wrap, it'll be in the color-shift satin white that has subtle gold, purple and green flakes/tinges depending on the lighting.
