IMO, people who buy dark coloured cars are stupid.

1. We’re in Australia, where the sun be fair beaming and dark colours soak up heat way more than a more reflective|lighter colour
2. Visibility of dark cars is worse because they blend in to the bitumen and concrete background at the best of times
3. Whenever conditions are poor (rain, fog, dusk, whatever) it’s by far the majority of dark coloured cars driving along without headlights on. My unscientific observation is that 90% of the cars you see in poor visibility without lights are dark coloured in any car shape. The other 10% are Toyotas which is probably because they have a dash that’s always illuminated which makes it less obvious if you don’t have your headlights on.
4. Dark colours look dirty about 4 seconds after washing them so you’re either constantly wasting water shining up your piece of coal, or you’re driving around in a dusty old bit of charcoal.
