Perhaps it should be mentioned that Firefox does not currently support datalist for anything but text. https://caniuse.com/datalist

(And it doesn't look like support will be added anytime soon: https://bugzilla.mozilla.org/show_bug.cgi?id=960984)

I’m not going to mention it, as I’d rather only worry about what’s the purported standard. But at least there’s this comment now. 😜

One strange thing I noticed: assigning a value to this component changes the look of the sample, but not the hex display. In other words, if we write viewof color.value = "#ff0000"; Then, the sample rectangle changes to red, but the hex code remains #4682b4
