While I am sure there are stylistic reasons for using that color, there is another common reason why you see blue-green colors in paint, especially in older industrial environments: zinc chromate/phosphate corrosion protective coatings. Zinc chromate primer is the color you see on the interior surfaces of some aircraft, to inhibit corrosion. Zinc phosphate is more of a gray in most cases, although varying paint chemi…

I'm reminded of an article a while back talking about how the change from sodium streetlights to LED streetlights had a whole lot of unforeseen effects on animals, people's sleep patterns, driver awareness and visibility, etc. due to color changes. There was a comment on the article from an old civil engineer saying "no, these were not unforeseen, we actually did the research back in the day to figure out what color…
> that's why they were the color they were That doesn't seem right to me. Sodium (and mercury) vapor lamps are the color they are due to physics, and were chosen because they're very efficient (and long lasting). Low-pressure sodium is the best and worst of these; essentially monochromatic but fantastic efficiency. Their only advantage, color-wise, is that the light can be filtered out easily (they used to be widely…
*edit: but it’s the overwhelmingly larger lifespan (20-30k hrs) that led to the wide adoption as streetlights. And I guess, the same is true for the change to led today, because of less power consumption.

Modern street lighting provides a way clearer view of the scene imo than the old sodium lighting. Maybe it's just brighter now.
It's about 100000x brighter and if your bedroom is next to a street lamp, good luck getting some sleep.

#99I asked about the horizontal colored bars painted on the wall in the lunch room. It was the strangest selection of colors. Each bar about a fist width. It seemed someone went out of their way to invent the most boring bland colors possible.
They told me the factory had spend over 100 k on a color expert to increase productivity. Everyone who worked there for some time knew this.
I thought I'd observe the effect. Someone was released from the factory floor for 10 minutes because they by accident worked enough hours in a row to be entitled to a lunch break, in their own time of course.
They sat down at a table carefully positioned to look straight at the color bars. And then it started! I could see on their face their internal dialog as if talking with the hundred thousand euro color consultant. The sandwich went only half way up to their mouth and they slipped into a catatonic state looking at the colors.
It was facinating, I just had to see more. Turned out half the factory had this moment with this colored wall!
I didn't have to ask them what that expression was. I could look at the wall myself and the internal dialog stated immediately: How the fuck do they expect me to pay my bills if I have to wait by the phone all week but only get two 3 hour shifts? Why did they have to spend a hundred thousand on colors to make me more productive?
It was impossible to think anything else. It was almost a blessing to go back to the high speed conveyor belt. If I didn't see it myself I wouldn't believe color theory works in magical ways.
