For me, the one big thing I like about the P5 is that it's not one of the "mono-color" schemes most other new cars are all about.
Our cars have liberal splashes of black all over the place, so the "best" colors are the ones which complement all the black accents.
For me, that would be the silver and the yellow, and everything else is second best.
The worst would be the black as that just makes the P5 another boring all mono-color scheme just like all the rest of the cars on the road, and the blues, as the black just doesn't go well with either of the blues, at least to my eyes.
On a more practical note, anyone living in the sunbelt should own one black car sometime in their lifetime - One will certainly do you, as you'll NEVER buy another one, not to mention that any black car looks filthy 15 minutes after you wash it. I had a beautiful black on black Supra that I dearly loved - Even more so after I had it painted bright white
Luckily, we all don't have good taste, or they'd have big troubles getting rid of all the ones they painted black or blue
The red and white ones look pretty good with the black, but neither holds a candle to the silver or yellow.
Tastefully yours
