My client had a white ceiling in her dining room and wanted me to paint it a bronze metallic finish.
After painting the ceiling, I stenciled a bronzy brown leaf scrollie design on the white crown molding, just under the bronze ceiling.
She had a beautiful crystal chandelier and it showed up BEAUTIFULLY!! with the dark ceiling background.
(Remember, metallic paints reflect, so they reflect where the light is shining on them. I think the flash of light from my camera made this show up really well.)
