IMHO, trying to match the color on a 14 year old red paint job by using the paint code, will only get you in the ballpark.
It will not be a perfect match.
And that may except-able to you.
However, if you want the touch-up paint to be a perfect match to the color your car is today, my advice would be to visit any pro paint store. For example, some NAPA and O' Reilly auto parts locations have a pro paint area inside.
Clean the car, take it to their location, and have them do a multi-angle digital reading.
Then have them mix the amount of paint needed for your application.
