I think there is a bug in `contentColorFor()`, when there are two *same* background colors in a color scheme, it will always return the *first* content color in both even if we use the second color.

I use `contentColorFor(MaterialTheme.colorScheme.surface)` but it gives me `onBackground`.

If `background` and `surface` are the exact same color, wouldn’t it make sense that `onBackground` and `onSurface` are also the same color?

No, in my design system, onBackground has less contrast than onSurface in dark theme.

Like the new text contrast feature in Android 14, they may be different.

That's interesting yeah, I guess it's not that weird of a thing. I'd file a feature request on the issue tracker and link it back here, to see what folks from Google think about this too.

Considering how this API works I don't see how it could give you the color you want when multiple colors are equal values.

Well, so do you consider replacing it with other API?
I have to add `contentColor` for all `Surface`.

Or I can add a small value to every channel of `background`.
