My wife and I felt very confident in our color selections. I have always wanted a Pearl White car and she loves the dark grey on her current vehicle and wanted to stay with the same hue. Then we decided to drive to our Tesla dealership and see the colors in person.
After seeing the colors in person I was not satisfied with the lack of pearl in the white (it looked flat white in the shade) and after seeing all of the other colors I'm 100% set on Red. It looked amazing in the sun and in the shade. My wife thought the grey was okay but didn't like the blue flake in it. She's now 100% set on Silver. Luckily we're both getting one so we don't have to fight over Red or Silver
My advise to all that are still unsure, take a drive down to a Tesla dealership. You may change your mind.
