I'm guessing these colors were used to keep the patients calm. Although according to this article: psychservices.psychiatryonline.org/cgi/content/full/57/10... the results of studies on the environment of a psychiatric hospital have been inconsistent.

Pretty simple image this morning. I love signs of industry, and I love realy simple scenes. So this is pretty much a win-win.
Photoluminescent exit signs do not require AC or electrical power. There is no battery or on/off switch.
How do they illuminate?
Photoluminescent signs require 54 lux or 5 foot candles of mercury vapor, metal halide or fluorescent lighting to fully charge and make them illuminate. The average office building has no problem meeting this requirement. In this charging process, photons are excited and then brought back to a lower state. The photons then will be absorbed by a substance via electromagnetic radiation, which will take these to a high energy state and then moved to a state of lower energy.
How long does it take a photoluminescent exit sign to charge?
A photoluminescent exit sign will fully charge in approximately 60 minutes. They stay at there peak illuminate for a minium of 90 minutes however it can takes about 16-96 hours in darkness to fully discharge.

Lee Wilson Disability Access Consultant, Person with Hearing Impairment looking at Emergency Message
this week the girls had 2 photoshoots, to really help us determine who should leave next, and who deserved to make final 5. leave a coo if you want but tbh irdc.
"you said i'm wise, but i'm not so sure.
maybe my lies were just that good.
.. and my lonely tears wish never to be
puddled on a floor with just them and me.
it's a long life,
a long life to be always longing.
there's truth in these eyes you can rest assured.
salvaged by voices that have no words.
a run-in with fear left ruin in its wake.
is the measure of a man how much love he can fake? "
