DH and I recently painted a room with Restoration Hardware Slate paint and it's a perfect dark gray for that room. I wanted to paint a nearby room with RH Graphite paint (lighter version of Slate) but my test area ended up looking super taupe/beige. "Greige" is the term for gray/beige, I guess. I tried the Slate on a wall in that room, and it ended up looking more like greige, too. I guess that room is very light, so gray paints read differently in there. It's just so weird that a dark gray paint can look taupe in another room. I had to find something else that would be a cooler (vs. warmer) hue for my unpainted room. I tried Benjamin Moore Coventry Gray and BM Platinum. I need the paint to match other grays on the floor + a blue-gray rug + a green-gray sofa. I never realized how many versions of gray are out there... blue, green, purple, brown, etc. Has anyone else tried to paint with gray?
