Not particularly on topic but I was scanning through some old Better Homes & Gardens magazines (pulp based social media) at a local estate sale and saw this ad for Westinghouse Light Bulbs from 1956. Most of us are now aware of LED based Human Centric or Bio-Centric lighting technology so I was struck by this early attempt to use colored light bulbs to influence mood and perception in the interior environment.

Not to mention the now inappropriate depictions and adjectives used to describe the various effects.
