The avocado plastic craze is one I remember well from my childhood. We lived in military quarters at the time, so extensive redecorating was out of the question and the only way we could "jazz up" the property to suit our tastes was by the use of accessories. If it was available in avocado, we had it; kitchen utensils, curtains, lamps and even bathroom fittings such as the medicine cabinet and toilet seat. All stuff that could easily be taken away at moving time, and replaced with the standard issue fittings that came with the house, ready for the next occupant.
We don't look back now and go "Eeewww" at the thought of all that avocado, rather it's something we remember fondly for being at the height of fashion for its time. Styles and tastes are continually changing, so today's decor isn't going to appeal in 20 years time either... it will be history repeating itself all over again.
