I saw a pearl white at the DC store. Thought it was very, very slightly grayish in color. The pearl did not standout for me in comparison to the Lexus pearl white; that is gorgeous. I am thus leaning towards the solid white with the gray interior. But I saw the tan interior on a white car at the Rockville MD service center and liked it too. I think the gray may be sportier and the tan mor luxury. But I am concerned that the piping on the tan would not go with the rest of the car, whereas the cream piping on the gray matches the headliner color (for the most part). The decisions are so hard to make.
