I while back I got a scratch across my driver side door handle. I went to the dealer and got the small touch up paint. I put it on myself and it looks like crap. Wrong color! The guy told me it was the right stuff even after I told him it looked darker! What I have is a zinc yellow and the paint he gave me looks more like that mustard yellow.

Is there a way I can fix this? It really stands out and I did a horrible job to start with.
