Over the past few years I have noticed that grey color cars are more often the color that I miss when pulling into traffic or merging. I decided to check to see if there were any studies done on traffic accidents and vehicle colors.
According to one source the following colors are more prone to accidents
Black
Grey
Blue
Red
Green
I was very surprised that red was one of the worst colors.
The following car colors have the least accidents. What surprised me was that, percentage wise, white had the least accidents . Then I decided to do a further check and white was more accident prone. Info here
White
Yellow
Orange
Gold

Here is a link to another source and they say that white is the safest color. Link
I presently drive a white van and as mentioned above I have problems picking up various shades of grey.
