Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. Eye‑fatigue‑reducing green
The sea‑foam/“Go Away Green” shade is repeatedly praised for easing visual strain.

“It really does reduce eye fatigue.” – d--b > “Reminds me of Go Away Green.” – ortusdux

2. Historical design origins
The hue traces back to mid‑20th‑century color theory, zinc‑chromate primers, and Faber Birren’s work.

“The reason for the green stairways was the vast surplus of the green paint (used for military equipment) post‑WW2.” – gukov
“They definitely knew, Soviet books on industrial design and architecture explicitly mention Birren.” – czwc

3. Practical/industrial constraints Cost, paint availability, and wiring‑color pragmatics drove the widespread use of the shade.

“Cheaper to buy huge spools of gray clad wiring than a lot of different colour coded wires?” – SoftTalker
“There are hundreds to thousands of wires in an aircraft, but there are NOT hundreds to thousands of different colors of wires...” – xethos

4. Community nostalgia and modern resonance
HN users express personal and design‑nostalgia connections, seeking the paint and referencing its cultural imprint.

“I would love to get an original copy of ‘Colors for Interiors: Historical and Modern by Faber Birren’ and create colour matches.” – srmatto > “#81D8D0 club, represent! Tiffany green is a Top10 /hn/topbar colour for a reason.” – ProllyInfamous
