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.

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

.
