I have found SEM to make the only decent interior colors. I had a interior piece color matched at the paint store and was happy with the results. The '69 parchment is a pearl and I am not sure but I believe yours is as well.
Of course this means you will be spraying the paints from a paint gun not a can.
for quick touch-ups this product is surprisingly effective, and its not just off-white!
check for 67,69 parchment... as 68 is different.
