I may be wrong, but i think that's a big ask, and could only come from DB archives, from the list of data cards issued?
If you search the members registry, which is obviously only a tiny representation of cars registered, and i haven't counted the full list, but DB571 only shows up for 5 cars, whereas silver accounts for about 90 odd, albeit some are silver blue or silver grey.
This isn't very accurate as search functions are limited, but if you have trouble sleeping one night, you could scroll through them and compile a list from the most common to the rarest, which might give you an idea
