Rick... gotta tell you, it's one of those things. The door panels are molded in plastic and the paint you used is just that... paint. I know... I know... pretty obvious. The whites are correct, it's a different technique to achieve the finished results. Especially when you mix and match vendors for your finished results.
It's like taking a picture out of a magazine of an unusual color, going to your local paint jobber and asking them to match it. You'll find that even the closest paint match isn't going to be the same as the colored ink used in the magazine. To totally different outcomes.
Even looking at your monitor on here, skimming through pics, is going to disturb the actual color to an extent. Yeah, it sucks, but it's the reality of the situation.
Take the door panels to your local jobber who sells SEM, have 'em scan 'em with a scope and get the paint that'll match the panels.
