Once you buy a pot of paint, you keep painting more and more objects with what is left. I experienced this with black spray cans (you might remember ;), and now grey is the color of the month.
One Arne Jacobsen ant chair still had its original color: light blue (the other two are now -big surprise- black). I just didn’t know in which color to paint it (
you have to stop painting everything black at some point). But after getting this color for the Ikea stools, it was a no brainier!
