White is the safest "color" and holds up best over time. Silver and variations are the most popular. Black shows dirt and absorbs sunlight. Red and Yellow attract attention including police speed trap attention. Blues are safe like silver/grey.
Don't buy silver. I did and I regret it. Apparently it's the least visible colour on the roads in daylight, so it's the most dangerous. Plus in some lights, when it's dirty, it just looks like someone forgot to paint it...
I had an irridescent Grossa silver Mercedes Benz that behaved like a chameleon. On a wet day it looked the same color as the road! But at night it reflected every color it was near, and it looked wonderful!
I have a very economical way of getting round. It only has two wheels and it runs on air.Costs nothing. Its navy and the air conditioning system is free. Sunburst Orange is good. My works well for me too.
