I really wish it were this simple. Which color Porsches sell for more? In fact, greens generally bring the greatest premiums as do blue shades. In all air-cooled 911's. Meaning, the questions and answers are just more complicated. Are we talking about Porsche paint to sample cars or are we talking about standard production colors? Are we talking about newer cars (e.g. 2013 to present) or older Porsches such as 993s and older? Try looking for the price of a Mint Green Porsche 964 relative to a standard black 964. Or a Blue Turquoise 993 vs a red 993. Unfortunately, you won't find a green or blue one for sale because they are that rare. Not to mention a purple shade. And if you find one, you'll likely be dealing direct with the owner and not an auction. They don't come up for sale that often unless it's a Japan auction or a German car. But, a standard "midnight blue" colored 993 will never sell for anything close to a Riviera blue 993.
