light silver is such an easy color to hide paint defects, and dirt hides pretty well too.
i would recommend silver for someone who isn't as anal about their car being clean as most stangers.
the only flaw, like darkfire said, its a pretty bland color. some people dig it, but its a personal preference. i enjoy the darker silvers like the dark shadow gray, i like black, blue, and metallic colors, cars that really pop when you get em clean. silver, i clean em, and look back at my work and think, wow, it doesn't look, THAT much difference. haha.
