Why So Many Control Rooms Were Seafoam Green

The Color Theory Behind Industrial Seafoam Green

Beth Mathews Design
@mhoye I see that we're still using some of Faber's color coding (e.g. safety green, fire red) and we've added some new ones (radioactive magenta). I'm curious if an authoritative document exists somewhere that we're still following in research and industry.

These colours went beyond the borders of the USA and Western Europe - you will find them in soviet-era interiors too.
I couldn't tell if it was copied because the industrialisation started with the equipment bought and imported into the USSR from the USA, or evolved (with or without influence) in parallel.
Also, likely, there is some overlap with the industrial design research and findings by the Bauhaus.
