Paint code Help

Not a dumb question. Unfortunately the custom work I did was not an exact science and I had to experiment a little. The type of pearl I used came in a little jar, not sure if it was even 4 oz. You could get it in several different colors. I used white on the truck I painted black cherry. There was a multi-color one I used over a black basecoat on another job. It was so highly concentrated you could literally just dip your stir stick in it and then stir it into a quart of clear and it would turn the clear very cloudy. Of course when you sprayed the clear it was really transparent. I mixed too much in the first time I tried it but after a little experimentation I got it right. I sprayed a couple of coats of clear with the pearl and then followed with two coats of straight clear. The reason I used 2 coats of clear with the pearl is it is easier to spray a second coat if you don't have enough pearl in the first one, if you put too much on with the first coat, you can't take it off.
I haven't used any yet, but they have the pearls in powder form now. I've seen the powder they use to mix factory colors and it looks like it would take more of it, possibly a small spoon of it in a quart. The best thing to do would be spray an old fender the color you are going to paint the car, then mask it off into 3 or 4 sections and try a little different mixture on each one to see the effect. It will be a little trouble but worth it when your car is gleaming in the sun and you're collecting all the compliments.
Good luck,
