I've noticed it happening, variations of 'current', safe warm/stone grays are taking front stage when I'm analyzing color ideas for a client. This past week I worked with two different clients that weren't afraid of color and I found myself having to turn off the neutral button in my brain. What a nice pick me up!
Gray is still the 'new beige' but you can fall into neutral land just as easily with this update and have one color staring back at you in every room. The trick to update a space without ending up just shifting from all beige or 'builder white' walls to all taupe or gray takes a little faith to think outside the conservative box.
