Grey cars break down than those of any other colour - and green is no lucky charm either, according to the digital motoring magazine imotormag.co.uk.
It has found that more than one in three of our 1.3 million grey-car drivers will require help from breakdown services.
As for green, owners of the nation's sixth most popular colour are the second most likely group to require roadside help.
But all is not as bad as it seems, since most of the callouts relate to flat batteries and punctures rather than mechanical failure.
Says editor Mat Watson: "The results are genuinely surprising. One theory is that many hire and company car fleets choose grey because the colour looks newer for longer, with dents and scratches less noticeable.
"These vehicles are often exposed to very high mileage, so perhaps their chance of needing assistance is greater. Then again, grey cars could just be cursed!"
The breakdown for colour and percentage callout is: grey 38.9%, green 36.7%, yellow 35%, gold 33.1%, white 30.8%, black 28.6%, purple 27.8%, blue 26.7%, silver 25.3% and red 25.3%.
