Why So Many Control Rooms Were Seafoam Green

The Color Theory Behind Industrial Seafoam Green

Beth Mathews Design
@mhoye I have seen a lot of old cast iron power tools in the hammertone version of this shade, especially table saws, but including also jointers, planers, drill presses, etc.
@vadhakara Yeah, likewise. Plenty of old shops have big tools like this.
@mhoye fascinating! Boosted.

Interesting article. I never really thought about the wall colours that much even though I have spent a lot of time in control rooms.

There are still a fair number of older industrial control rooms in those colours. Newer ones are more often just off-white.

Most panels are still ANSI 61 grey though unless they have a special status/function.

@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.
