Not true, painted my demon with trunk hood and doors off, but painted at same time as body and you cant tell at all.
A good painter should be able to paint the car with the hood doors and trunk off and it match unless its tri coat such as pearls or candies/flake then its more difficult but solid colors and metallics are not a issue
My dad painted my demon and painted hundreds of cars and has done paint/body/frame work for 30+ years, every car they did a full resto on at the body shop he worked at when he painted them the doors hood and trunk were always off and sometimes the fenders, never had a problem with color matching.
Having a good quality paint and clear helps too.
Doors trunk and hood off my demon were painted flat on stands, had no issues with color match
Todays coatings are formulated with the idea of 'spray to hide', once hide is achieved, THEN STOP! It's done to try to make it easier for painters. Good painters it won't matter, they just know, but those with less experience, this helps a lot.
