I have a weird behaviour right now with TopAppBar only when darkMode is enable. If

elevation = 0.dp

the background is correctly applied. If the elevation is by default, the background color is different (more bright). Is this an intended behaviour or a bug with beta01 ? Also it's only with the black color from Compose (

Color.Black

), I tried with other colors and it's working fine 🤷

It is the material design specification. https://material.io/design/color/dark-theme.html#properties

The higher a surface's elevation (raising it closer to an implied light source), the lighter that surface becomes. That lightness is expressed through the application of a semi-transparent overlay using the On Surface color.

Ah that's why

Thanks @Andrey Kulikov 👍
