I guess I'm wondering how "stone" compares to gray. Is it lighter or darker?
I'm going to get leather and I'm going to go for a color that matches the gray accents of the car. I don't want anything as light as the seats are now.
Stone and lt grey are close the same value. Stone has a bit more brown tone to it.
Dove grey is the factory recommended match for the light upholstery but like you we would like to go darker, something matching the dark component of the dash.
