Recent research in the USA would suggest that silver cars are less likely to be involved in crashes. This is interesting because it goes against the grain of established knowledge, namely that all pastel or light shades of colors are harder to see when the light levels are poor — such as dawn, dusk and in bad weather. So what was the perceived reason for the “safety” of silver? Simple! Silver cars are currently seen as being expensive status symbols and are therefore generally driven more cautiously, by somewhat more mature people who are in the age bracket where cautious driving is more to be expected anyhow.
