When it comes to visibility, the most invisible to me is dark green. In shadows or at night, harder for me to see dark green than even gray or black.
It's interesting too how some designs and colors go much better together than others. We had a 1997 Olds 88 that looked great in teal green but awful in white or silver, colors that we usually like. Some colors just go better with certain designs, but I can't figure out why.
