> You would expect an explosion of color in the 1960s and then a decrease

What happened was a lot of muted colors, earthy yellows, browns, and oranges in the 70s followed by an insane amount of the brightest colors possible in the late 80s and early 90s where fluorescent blues greens and pinks were everywhere. It seems like everything got a lot more bland after that and we've never recovered to happy medium.
