I was looking at a recent photograph on-line, and noticed that one of the walls in the background was pastel green. It struck me that pastel green is a color that was very popular in the '50s and in the '60s, but since the '70s almost complete absent from every-day life except for
vintage appliances and furniture.
Nor does it seem to be a color popular amongst those who otherwise enjoy such items. I certainly don't miss it; I wouldn't much care to have any of those pastel green vintage items in my home. But those attempting to recreäte the authentic look-and-feel of 40-to-50 years ago probably should make greater use of it.
