I think `black` and `white` should be switched here:

color: light-dark(black, white);

I don't think so. You want black text on a light theme/background.

But why is the order switched below?

Functional notation: light-dark(light-color, dark-color)

It's not.. `light-color` refers to the colour you want presented if the user's preference is for a "light" theme.

It's not declaring the relative brightness of the two colours - I agree it could be documented a little less ambiguously with something like `light-theme-color`.

I got confused because I thought it would set a background color. For text it's inverted and hence correct.

It sets the foreground/text color because it's used with the `color` property (https://developer.mozilla.org/en-US/docs/Web/CSS/color). You can use it to set the background color too in which case you'd do `background-color: light-dark(white, black);`

Sorry, I misread your answer. You're right. I automatically assumed setting some background color for which `color: light-dark(white, black);` would be right.
