Car colors
 

Good article citing a PPG study on car colors that Americans buy - silver comes out ahead at around 25% of all cars. Specialty Colors (guess yellow is in there, since not mentioned elsewhere) at 3%. New things coming up: liquid looking paints, sparkling paints, and more. Says something about broadening the palette in the future - more colors?
When does paint spray technology get to where we can choose from an array of colors, designs, accents, etc. from a large book of choices and get it straight through the dealer at reasonable prices? Cars are a major personal expression - bet it heads that way. Dealers already have more wheels, etc. than before. People like to customize their rides.
Side note - I think Porsche was in early on custom colors, but very pricey.

Oh yes, Porsche's Paint to Sample Option on the 987 (#98- non metallic and 99- Metallic) is $4,315! This option includes a production delay of 3-6 months.

You can also have a custom color on the leather. That will run ya $3,845.

Definitely a lot of money, but pretty cool to think that you can really have anything that you want...and be the only one with it!
