Those items can defiantly play a part in matching the paint. I initially was going to fog into the door, but decided to see how well it matched first. I figured if it didn't match it wouldn't be a big deal to go into the door, however this is just to far off. When I purchased the paint I had to choose between three different chips as this paint code is a variant formula. I ran across this same issue on my Taurus and had five options.
