Why is the world losing color?

It's not "losing" color.

At periods when technology resulted in new color possibilities, people went overboard with color. Make all the things colorful!! Think of the technicolor sixties. And we can go back in history and see the same thing with new clothing pigments, new paint pigments.

But when everything is colorful, nothing stands out. Everything being colorful is as monotonous as everything being, well, monotone.

Modern taste is more about more neutral-colored foundations with color accents. Don't paint a whole room green -- have a gorgeous green plant that stands out all the more against its neutral background. Don't paint a whole wall orange -- have a beautiful orange-hued piece of art on the wall. It's just more tasteful to use color as one element, along with size, shape, texture, and so forth. Making it the main element in everything is just overdoing it. It's bad design.

I don't want constant "riotous color", as the article puts it, in my home, or my workplace, or while I'm driving. It's visually exhausting.

could a factor driving current monotone style be less about aesthetics and taste and more that we're all just cognitively exhausted?

everything is fighting for our attention because our attention has been monetized. so when something bland shows up, it simultaneously provides a bit of respite and can seem more 'trustworthy' because it isn't clamoring for your attention.

if i were buying some kitchen appliances and i had a choice between a brightly colored models or a stark, utilitarian models, i have to admit that the stark ones have appeal because they "look professional" (even though it may not actually be pro quality) and "the color is just a sales gimmick" (even though boring industrial grey is also a sales gimmick)

I think the sensory load idea is productive, but I'd add a related idea of drawing attention to key things only.

I don't care if my kettle looks "professional"; one is pink, another is orange.

But I prefer walls around me to be white or very lightly colored, not, say, intensively red. That would constantly distract me.

Code in my editor is colorful like a Christmas tree, bur most of the interface is muted beige and green. This is about certain things requiring my attention, and others sparing it.

When everything is loud, nothing is, nothing stands out. Bold colors often work better as accents.

(Sometimes it's about non-aesthetic considerations. I prefer my car to be approximately white to soak in less of the hot summer summer sun.)
