Mine is this little tidbit about Khaki’s from https://www.heddels.com/2019/05/history-khaki-anything-drab/
“Tried and tested by all the major powers, khaki-dyed, lightweight cotton twills became the de facto uniform for any colonizing power. If you were going to ship your boys abroad to pillage and conquer someplace in the Southern Hemisphere, khaki was your go-to color.”
“Blue lights on train platforms in Japan have been shown to reduce the chance someone will jump in front of a speeding train. In fact, one study in the Journal of Affective Disorders found blue lighting reduced suicide attempts by 84%. It’s believed blue registers as a calming color, associated with the sky and sea, which may be soothing to people in distress, according to Psychology Today.”
I guess people who keep using blue-light filter glasses at end of work will miss this.
Lol dark thought at the end
