except MTI are black......Just a worthless observation, but it seems that the fastest C6s will be black for the near future Not taking away from MTI, just the black C6s will outnumber their yellow one(maybe the yellow will be the fastest).
It is well known that certain colors are heavier by virtue of the added layer such as in the case of the pearl colors adding at least a pound or two with 3-4mils of paint thickness. That results in a heavier car and the black cars may well have a serious edge here.
Cartek having the edge on the science end of radiant energy, has a car that resists heating up as fast in the sun as black absorbs far more heat from the sun than precision red will so his car will run cooler.
You thought there was no reason for it but there is.
The yellows turn heads and those cars will be the slowest as more girls will take notice and hold the driver up while he gets tele numbers.

This is very good information to know. By virtue of the added weight from the black absorbing the energy, the vendor smart enough to pick white will probably come in somewhere in the 6 x 10^-28 kg range lighter. That is probably good for at least a .5 second reduction
I appreciate the thought provoking facts but if you post on this forum, we would appreciate a non-metric conversion of your terms as this is about an AMERICAN car

What people forget is that black also radiates heat better. That's why radiators are painted black and why people in warmer climates evolved to have darker skin. Black is better for keeping something cool when the majority of the heat is generated from the inside (such as in an engine bay or inside a warm-blooded animal.)
Unfortunately, black seems to attract every speck of dirt in it's vicinity, thereby losing it's aerodynamic advantage that it has due to the boundary of hotter, thus less dense air surrounding it's skin!
Now which is more dertrimental? The denser air around the yellow one? Or the friction of the dust around the black one? Just something equally useless to ponder.

Darker skin has more melanin pigment in the skin to absorb more light. This helps prevent damage to the underlying structures. So, darker skin should be actually be slightly warmer....

Increased sectional density and frictional resistance...
It seems evident from prior posts that most members espouse the theory that black C6's absorb more heat and because of the imperfect nature of reradiation from a finely polished (and waxed) surface, the net result effectively being a net heat absorption resulting in a relatively linear expansion dimensionally increasing the gross frontal area and in addition the resultant increase in surface area of the effectively volumetrically larger car due to this heating will combine to reduce the ballistic coefficient of the C6.
We are not talking light years per nanosecond here, but it should be obvious to any seasoned CF member that to obviate this effect would require a change in the relative surface radiation/absorbtion ratio coefficient.
This, of course would be best done by sandblasting (a relatively inexpensive process-even allowing for the "Corvette Tax"), in order to increase the ratio of re-radiation in order to cool the car.
Those of us who are older will certainly remember how cool to the touch and fast our black primered 50's era machines were!
I think it's great how we learn from each other here on CF, and I for one am just elated to be able to share my extensive knowledge and automotive experience here on CF, especially with you newer intellectually and mechanically challenged menbers!
Sincerely,
Roy
I notice that trying to write like a certain John Kerry talks is difficult!

This brings up another very important issue. There has been a lot of talk about the orange peel surface and it seems to me that most are just jealous that it really a fully "orange peel" surface. The sand blasting would more than take care of that issue, and just like a golf ball, the slightly concave surface would increase flight time

There are chemicals that people could have evolved to use that are lighter in color and do the same thing. That the color is darker demonstrates the same effect found when painting radiators black. How many cars do you see with white radiators?
