Correct. But it is not that simple. The black absorbs sunshine through the full range of sunshine frequencies that impinge on it, mostly in the visible spectrum, and all this absorbed energy is used to heat the black surface. But while radiation is emitted just as readily from the black surface as it is absorbed, this radiation is restricted to the bandwidth of the black body radiation spectrum for a body at that temperature. The sun has a much wider bandwidth - the car will not radiate at the same rate as it absorbs from the sun until it reaches the same temperature as the sun!
What confuses the experience is that for most modern cars, heat absorption from the sunshine entering the windows, mostly at low angles to encourage solar heating by designers who live in cold climates, greatly outweighs the effects of body colour - interior colours are more important. This heat is trapped inside by the greenhouse effect - the glass is transparent to visible light, but opaque to infrared. This is less important for Defenders with their relatively small, near vertical glass, and is also reduced on other vehicles with heavily tinted glass, although this is less effective than you might expect seeing the windscreen, which is usually the main culprit, cannot be heavily tinted.

Interesting thread.
We have 2 new Hire Cars coming this week-end. 1 is Black the other Dark Grey.
It will be interesting to see how difficult it is to keep them looking good for the 5-6 years they have to last?
It will also be interesting to see if my staff can clean them without scratching them.
Unfortunately they were Demonstrators, not brand new so I had no choice on the colours but did save a sheep load of money since the both are under 1000km.
Really unfortunately they are Nissan X-Trails not proper cars at all (LAND ROVERS), but will have to do.
Apparently both my Bosses & the people that hire our cars have no class or appreciation of the finer things in life, so we cater to the Plebs!

I didn't take any of the cars in Rome or the crumbling real estate, but this is my view overlooking Lake Maggiore and the Swiss Alps.

That is a common phrase in png, but you now have me wondering about my red leather in a black defender.
Black is very nice, but i do regret not getting Keswick Green and a white roof, as oh so many advised.
Another challenge for the new defender, Keswick Green option
By all means get a Defender. If you get a good one, you'll be happy. If you get a bad one, you'll become a philosopher.

SubscriberRACQ ran tests on white and black cars. There was almost no difference to the temperature inside the vehicles. Black car did eventually get hotter, but not significantly.

Gotta be Keswick for sure,...love a limestone roof too,...absolutely classic, but we've got an Indus roof, from the factory, I don't think anyone else has that combination!!That is a common phrase in png, but you now have me wondering about my red leather in a black defender.

Why isn't the roof of all cars made of Solar panels which run exhaust fans (& input fans) to keep the car cooler when it's parked in the sun?
