Can anyone help me understand why constructing a MaterialTheme object like this

MaterialTheme(colors = darkColors()) {
    Text("Hello, world!")
}

doesn't change anything? The surface color should be 0xFF121212 (dark grey) and the text white, but my app still opens with a white surface color and black text which is the default light theme color.

Seems like it's straightforward to change the theme, so I'm not sure what I'm missing here.

You're missing a Surface

As @Big Chungus said, you need a surface that will read MaterialTheme.colors.background

The window by default does not apply any kind of theming.

Oh that's interesting and a good lead. I'll follow that and hopefully sort it out. Thank you both!
