Actually, it does make more sense that “Marine” is a blue color

You may be familiar with a feature on your operating system that makes everything yellowy-orange in the evenings to reduce the amount of blue light that gets blasted at your eyeballs. The idea is that this is equivalent to wearing blue-light-blocking glasses, and will let you get sleepy at normal times instead of tricking your circadian rhythms into keeping you up because your body still thinks it’s daytime. Apple calls the feature “Night Shift”, while Windows calls the feature “Night Light”. On Android, I gather the feature is called “Night Light” (“Eye comfort shield” on Samsung devices). At any rate, the original program that started this kind of thing is called f.lux.

At any rate, there are consequences to making everything more yellowish-orange. The most obvious thing is that you shouldn’t do color-sensitive work. The first prohibition that comes to mind is “don’t do anything in Photoshop unless you’re doing black-and-white pixel art or just cropping things”, but this also extends to other tasks like “don’t go clothes shopping”.

That’s not all, though.

A while back I was picking out a cover for my iPad. I saw a nice green one in a color called “Marine”, and I bought it.

When the thing came in, it was blue. I like blue too, so it’s not like I was mad or anything, but I was puzzled.

It took me a few hours chewing on how I might have thought I was buying a green cover before I figured it out.
