Color is a personal choice...Best way to select which color to take is to see different color civics side by side... that is possible in showroom but due to lighting and zero meter condition, the color you will select may not look the same it will be on roads with normal maintenance.
When I visited Honda showroom, fortunately all colors were present there and the color which to me was looking the best among all was Modern Steel Metallic - it has great class... next best were Black and White.
In my office parking lot, there are Silver, White and Modern steel metallic Civic Oriels... The Silver in Civic Oriel looks too ordinary and dull compared to the other two. Modern steel is good, but when that car is dusty, the look is not that great - plus in sunshine, it does not look as good as when the car is indoors or in the night. The all weather color is White - which looks good in all lighting/sunshine and car condition. If I have to buy a Civic now I'd go with White - even though it is most common. If I'd be able to keep my car polished/fully clean all the time, then Modern Steel.
