Well, as you've found out, visual tests are misleading -- unless you get lucky -- because texture and light source matter so much. Paint stores have a paint matching device that looks at how various colors of the light spectrum reflect from paint samples. That's the way to get the best match possible, but a sample of the original is needed. You did it exactly right to get a sample that was clean and had not been faded by light exposure.

Given that the thread is two years old, he's probably solved the problem by now....
Why do people think it's important to point out the age of the thread when it's a thread containing general information? There's obviously nothing here that's specific to the OP's situation. In other words, the OP isn't the only person in the world who has ever wanted to match some existing paint.
