My family has three cars. A red van, a teal truck, and a darkish blue van.
I think that the safest color for your car is any color that stands out against the background.
That means no:
• Silver cars (Too bad, I like silver...
)
• No dull colors*
• No light tans
* The reason for no dull colors is that all things that are outside in the environment always get dulluted and thus the colors get dull. You don't want your car to blend in perfect with a bush/tree or a building and specially not the street.
Orange is a good color. Either a bright orange or a bright green.
