If you're stuck on choosing what color to paint a cabinet or a bookshelf, try going with the wall color. Especially if your walls are a more dramatic color (this trick is a lot less fun if your walls are a very pale neutral or white).
I tried it first here in my office and then two more times with different client projects, and I'm just floored every time at how much I like the look. When furniture matches the wall color it gives the space texture but doesn't break up the flow of the room in the way that contrasting colors can.
I almost sold these fretwork cabinets a couple months ago because I was bored with them, but they really are the perfect size for my office and they provide some much-needed storage (as seen here). Painting them the color of the walls (BM's Chelsea Gray) gave them a second life for me, and now I'm glad I held onto them a little longer. Man, I've got to stop flying through furniture so fast! Do you get sick of stuff like I do? My furniture attention span is shrinking like crazy the longer I'm in this business.
(PS I lightly sanded the old paint job before brushing on the new coat of gray paint. I used a paint+primer formula, so I didn't bother to prime first. And I didn't use even an inch of painter's tape on all those tricky fretwork pieces because this totally works every time.)
HAPPY WEEKEND! xoxo
