touch up paint

[wingski]

I need some touch up paint for my ’29 cabriolet. The color looks close to the stock color on the ’37 Ford coupe I had, but I’m not positive. The online paint charts I’ve been looking at show an Andalusite Blue for the upper body, but that blue looks a little darker than what I’ve got. I don’t want to use a darker pain, but a little bit lighter would be OK. Ant suggestions? I’ve included a picture that shows the true color of the car the best.
