Doubt the guy at Lowe's could do anything with the F&B formula. You can order F&B online. I order samples and gallons from their website. Super easy.

You could also order a sample of Orangery, paint a sample and then try to have someone color match your painted sample. With that said, color matching F&B isn't always spot-on. But if you can live with close enough to the real thing, then that might be an option for you.
