Welcome to the site!
The color of your car should be up to you. We could all suggest the color we like best, or show what the most popular color is, in which case you could check out this poll. Perhaps you could tell us if you prefer light colors or dark colors... you have white & silver (light colors) & blue (a dark color) in your poll, so I'm not sure what to suggest as they're all good colors, but the dark will show more scratches than light. If you haven't already, try to check them out in person, in the sun & shade.
FYI. The plastic protectors on the lower side panels make the white color look off-white. My wife noticed it at the dealer when we were waiting to purchase our xB. I didn't get white, so it wasn't a concern to me. Good Luck.
I personally love the dark colors but I live in Arkansas where it's hotter than a kitchen in **** all summer so, I always get white, it stays cooler and doesn't seem to show the small scratches etc that you pick up over the life of the car. I wish they offered a pearl white though... My last car was pearl white and it was beautimous!
I got classic silver and in Pittsburgh it's great in the summer since it doesn't get to got inside the box and in the winter in doesn't show the salt quite as the white cars. But idk if you get a lot of snow. If any.
