OP, you will have another problem once you get the name of the correct color, this paint will have faded over the years, I have a neighbor that after several tries has not been able to get a match. IMHO, I would be prepared to paint the entire wall, and hope the color is close enough that you can stop at the corners. Also, if the paint store asks for a chip to match, ask how big the chip has to be, and if you have stucco, getting a suitable sized chip can be difficult. You will also need to match the finish of the paint, it appears that original paints were mostly a FLAT finish, we will be getting a satin finish when we get our house repainted.
I have no idea if any of the house painters offer a color matching service, but i am sure they will not paint a patch and will only paint an entire wall.
Hope this helps, and I wish you good luck with your project.
