Fifty Shades of Seafoam
The Color of Safety
Internet turns safety green into a Cold War paint fight
TLDR: An essay says seafoam green wasn’t just decor—it was a safety tool, part of a color strategy for human-run control rooms. Comments erupted into a nostalgia vs. functionality brawl, with Soviet cockpit turquoise and NYC subway colors cited as proof that paint still quietly steers how people work.
A think-piece on why mid-century control rooms were painted seafoam green lit up the comments—and somehow became a vibe check on engineering culture. The piece name-drops color guru Faber Birren and argues that paint is a cheap, powerful way to guide human behavior in control rooms. The crowd? Half fascinated, half roasting. One camp insists color is real engineering, not “decorating,” pointing to Soviet-era examples like turquoise airplane cockpits—yes, a commenter even brought receipts with a link. The other camp fires back that engineers treated humans like “flaky components,” so of course they sidelined color, and now everyone’s rediscovering mint as if it’s a new feature.
Nostalgia vs. functionality is the big clash. Is seafoam soothing or institutional and soul-draining? One user compares it to the old NYC subway mosaics—colors you “absorb over time,” not read like labels—with another link. Meanwhile, jokesters ask if we’re about to have a teal vs. green “Yanny/Laurel” for control rooms, and whether the “hex code for safety” is just bureaucracy in disguise. Accessibility die-hards crash the party to demand palettes that work for color-blind folks, while dashboard veterans snark that “red means bad” isn’t exactly a breakthrough. The consensus? Color quietly runs the show—and the internet is suddenly very opinionated about paint.
Key Points
- •Faber Birren pioneered systematic use of color in mid‑century industrial interiors to influence behavior and safety.
- •Color is a low-cost, robust design variable effective for human-in-the-loop control, via paint (persistent) and LEDs/screens (dynamic).
- •Control engineering education and literature largely omit color, as noted even in historical works like Mindell’s.
- •Automating responses to color is difficult, requiring cameras and computing, so engineers favor simpler sensor signals.
- •Human variability and the aesthetic/psychological dimensions of color lead engineers to avoid it, leaving color to designers and psychologists.
