Spray paint with dark color? How about lacquer?

My door are stained, not paint. Stain will still see the wood grain. The first color layer is spray but final coating if not mistaken the lacquer with normal brush. I don't see uneven brush line.

And what hinge do they provide? normal local? China? or bearing hinge? All made closing & opening feel difference.
