Where can you get the right color that matches the body color. 1926 Winsor Maroon. First try was use the color numbers in the information section on this site. Sturdevants said no problem. That should have turned on a light. First quart, $80.00 looked like a red/brown. Said they could not do anything about the off color. Sturdevants said they could take a picture at the paint store and mix it on the spot. Went to Sioux Falls with the hood. Second quart $56.00. Now it looks wine/purple color. Maybe I should paint the car to match the wheels. Who mixes good paint?
I would paint it red/brown, with wine/purple wheels. Matching paint can be tricky, and needs to be done by a good mixer- maybe a restoration house can help, they have to match h all kids of older paint on original cars.
One of the problems you encounter is that the paint on your car has faded, and paint in the can never looks exactly like it will on the car.
Some pigments fade faster than others (yellow is the worst). All pigments fade in sunlight, to some degree.
The color matching computers use reflected light, and they are designed to look below the top layer, to the best that is possible.
And then, after a month of drying time, the new paint will have changed color itself - just waiting for some strong sunlight to start the fading process. That's because the solvents, that evaporate in the drying process, change the color of the pigments.
You may never be able to get it to satisfy you, if you're trying to match a car that was painted a couple of years ago. The best idea is to purposely use contrasting colors in different areas, like on the felloes and the spokes, or the top irons.
Also remember that in the time it takes you to get home with that quart of paint, the pigments have started to settle out. When the instructions on the can say to mix thoroughly before, and often during, painting, they aren't kidding!
Try painting the new paint on a piece of scrap that has the same under-color as what you're going to paint, then use your wife's hair dryer to thoroughly dry it, and then leave it out in the sun for a few days, before making a final judgment. You might be surprised how well those cans of paint match, when you do that.
But it's a crap shoot, no matter what you do.
You could always paint them black.
You need to ask around and find a paint store with an employee that can mix and match color by eye. When you shoot a panel with a color matching camera (such as Prophet Spectrophotometer) it's not creating a custom made formula for your application, it's simply picking the closest thing in its database.
I see your car in your profile (nice Fordor, by the way). There are issues with color matching across brands or types (lacquer vs. urethane) but for the most part there's no reason a skilled paint mixer shouldn't be able to pin that down close enough that most people will never see the issues due to color shift. You may have to visit a dozen stores, mixers with the skill to match by eye are less and less common, but there's likely one somewhat near you unless you're very rural.
