Same when we sold our house. We had some pretty muted pastel colors in our rooms, nothing flamboyant like bright pink or whatever, and the first thing our realtor said was "we need to repaint everything light gray." We also offered to leave some of our furniture around in order to make the home appealing and show better. Again, nothing wacky, just a few sofas, tables and generic non-family pictures on the walls. Realtor said "nope, you need to stage it for 30-40 year olds" (with the most generic, bland, airbnb-like non-furniture I've ever seen). I can't argue with the results--she successfully sold the house in the recent toughest house market we've seen in 10 years. But, wow, that's the aesthetic now??
