I would get a yellow 911 !!!
Here is my vinyl wrapped BMW - as you can see it was black.
Plus you can easily see yellow accentuates the cars lines more than a dark color.
My current 911 is Shark Blue - I had considered Gentian but I thought after a couple of years it’s one of those colors that looks “tired” and is like any other Porsche.
Yellow is a “happy” color !!!!
