    I got through this entire article before I realized it was written by someone I worked with back in my agency days. Beth is an awesome designer with a great eye. Nice to see her on the front page here. Now, to the content: I often wonder how much we have lost with our endless quest for minimalism. We can't even make buttons look like buttons anymore. Affordances have become anemic at times. Designers who think and care deeply about functional color theory and usable design should be cherished.

      I'm reminded of an article a while back talking about how the change from sodium streetlights to LED streetlights had a whole lot of unforeseen effects on animals, people's sleep patterns, driver awareness and visibility, etc. due to color changes. There was a comment on the article from an old civil engineer saying "no, these were not unforeseen, we actually did the research back in the day to figure out what color the street lights should be, that's why they were the color they were."

    > We once went on a tour to spot bald eagles in West Tennessee, and upon arrival, a woman with fluffy hair in the state park bathroom told us she had seen 113 bald eagles the day before. We ended up seeing (counts on one hand)…2.

    As a semi professional eagle enjoyer, if the day before was trash day, then she might have been telling the truth. I’m not joking, they have bald eagle proofed dumpsters in Alaska.

    They’re basically smart seagulls with talons.

      We took a trip to Alaska via RV, and were parked at a roadside. I got up at 11:30pm at "night" (broad daylight) to use the restroom and was so annoyed by the seagulls I went outside to yell at them.

      It was eagles fighting over a salmon. They genuinely do sound and act exactly like seagulls.

    Reminds me of turquoise cockpits [0], another workspace where visual fatigue considerations are important.

    Reminds me of Go Away Green - https://en.wikipedia.org/wiki/Go_Away_Green
    • dylan604 30 minutes ago
      Go Away reads to me as a command to the viewer to go away rather than the intended "we want the object to go away from the viewer's thoughts". If they were okay with a phrase like Go Away Green, why not something like Hidden View Green, Irrelevant Green, Don't Look Here Green, etc. Some PR department would have a field day

        Prob because Go Away Green sounds way cooler than all of those and it’s not a user facing term anyways.

    It's so nice to see colors in any kind of government, industrial, or commercial building. The "everything must be gray/beige" fad has dominated institutional interior design for at least 30 years. Maybe it's just nostalgia, I remember the wall colors in banks, schools, doctor's offices, mcdonalds, and so on in the 1970s and they seemed so wonderful. All these things got a coat of white paint sometime in the 2000s and look the same as everywhere else now.

      I feel that too. My house had significant chunks painted a vivid aquamarine when I moved in 2018, and my now-ex insisted that we paint over it all in grey.

      After she moved out, I put up greens, yellows, brown, and blue all over the house. It's not quite as "public pool" feeling as that original aquamarine, but it's certainly more lively than grey/white. Funny enough though, when I had a designer come in to take measurements and do a mockup for a kitchen reno... everything was back to white because that's step one in making it look "modern" even though part of the pitch is custom cabinetry that won't just look like that same white IKEA stuff that everyone installs now.

        It's common for homes especially when prepped for sale because neutral colors won't clash with whatever the potential buyer might want to bring in e.g. furniture, artwork, or other decor.

        Most of the rooms in my house are painted in colors and I mostly like it but it can sometimeds feel fatiguing. I've thought about repainting in a neutral gray or green.

        Install the boring shit and use colored vinal wrap for fun. Good resale value and you can enjoy life.

      I had to get my whole house repainted after a kitchen fire. Have some black and a lot of white (trim and ceilings) but also subtle green in upstairs rooms and very subtle orange everywhere else. Kept it simple but prefer it to everything being a light gray like a relative has. There still aren’t that many different paints if retouching is ever needed.

    TL;DR: because mid-20th-century designers believed soft green reduced eye strain and improved focus.

    Basically the same nonsensical belief as in regard the dark mode nowadays.

    I wonder if the designers of cold war soviet planes read the same color theory because their cockpits are always a very particular indescribable shade of green. There were also very specific colors for subsystems, yellow for fuel, purple for hydraulics etc. Much more than the contemporary US designs.

      My father was a mechanic and crew chief working on F-14's during his time in the air force. His two takeaways from his service were: 1. No one should ever join the military for any reason ever forever, and 2. Somebody needs to color code literally anything.

      He talked about how the wiring schematics were a maze, made worse by using only non-labeled gray and black wires with connections and mounts that were the same color made of the same material.

      The exterior being gray makes sense - harder to see with human eyes. But internals? They should be massively contrasting colors for every single series of pieces to be removed so you can just follow along by color.

        Cheaper to buy huge spools of gray clad wiring than a lot of different color coded wires? Also you don't have to stock a lot of different colors for repairs.

        Tangentially, this reminds me of stories from my dad who got some kind of special award for having made their ship radar the best in the fleet.

        Sometime before that, he got a lot of flak for having neglected one of the standing rules, to label everything as you take it apart and put it back "the way you found it". He decided to break it down and put it back the way the technical documentation said it should actually go. This seems to be part of the reason his radar performed better than the others after teardown maintenance.

    This article is a gem, thank you. Now off to Sherwin-Williams to see what the equivalent color names are. I wonder if there are matching formula.

    Old school SCADA screens that I first saw had a similar green background.

    Have always been a fan of colors like that for my desktop background. Maybe because it's calming and I don't realize it?

    I'm not sure if it started with the teal from Windows 95's default color (hex codes vary based on Google searches), or if it was a purple-ish color from a classic Mac from school.

    To this day, my work Mac is teal and my personal is purple.

    Tiffany green is a Top10 /hn/topbar color for a reason.

    Some of the old retired US aircraft carriers have their control rooms painted this color.

    Su-27 fighter cockpit is known for its turquoise paneling that supposedly is to promote calm.

      Yeah I was about to say similar pastel green colors crops up in a lot of Soviet control rooms too.

    On US submarines, every bulkhead and beam not in the bilge is painted seafoam green. We were told it was the most soothing/ anti-rage inducing color possible - necessary for long deployments in cramped quarters.

    After a little over a decade of service, no other color infuriates me more

      Silver lining, at least your triggered by a color that basically doesn't exist and is no longer in wide spread use. (As in you won't find it as much in daily civilian life)

    > He painted his bedroom walls red vermillion to test if it would make him go mad.

    And? Did it?

    That’s a fascinating story!

    I’d never even heard of this guy.

    Ha, I am very proud that I made that discovery independently as well. In the Light vs Dark theme, I settled on a light greyish green that is somewhat close to the one described here. It really does reduce eye fatigue.

    Half arsed article. Expected much more detail
