Thank you! I liked the darker silver but can always hear my parents saying never to get a dark colored car - hard to keep clean and harder to see at night. This is a hard color to describe. You'll love your car regardless of the color really - and I can't even see the exterior color from inside - so enjoy what you ordered! It'll look great! What color did you settle on?
Dark colored cars also absorb more heat in the summer and lose heat faster in the winter. If you are out on a night when it's just beginning to get cold enough for frost to form, you will see the dark cars form frost before the light cars do.
I've noticed a difference in the sun between black cars and white cars.
Between the keeping clean thing and the heat loss/absorption issue, I've been driving white cars since the mid-80s. My SO was a little happier that I went with the pearl white instead of plain white on my Model S.
