I'm by no means an interior designer, but my sense is that 60s/70s European design is pretty timeless. Especially if you take out the boldest colors, plastic-sheathed couches, and the like.

My sense is that modern furniture has generally fairly simple lines--and, from what I understand--younger generations tend to favor neutral color tones. While my house is relatively muted, it isn't the greyscale that I see among some younger folks.
