In the magazine there is room done in a pale, pearly gold (called Veil Cream) that manages to look really sunny and glowy with the white furniture and silver accents used in the room.
It's a subtle effect, but it looks fresh after years of flat matte walls.
The Studio Finishes line includes 5 metallic glazes. There are also 30 mixed colors with a metallic/pearlescent base.
A quick online search found them selling for $25 - 30./quart.
