I am not able to use `MaterialTheme.colors.onSurface` in a Composable. Cursor hover tells me
`org.jetbrains.kotlin.diagnostics.SimpleDiagnostic@9406416a (error: could not render message)` whereas the build window tells me `@Composable invocations can only happen from the context of a @Composable function` But I am using it inside a Composable function.

It must be directly inside @Composable function. My guess is that you are using it inside `remember {}` but I can't help you without seeing your code.

```@Composable
fun Test() {
    MyTheme {
        Column {
            Canvas(modifier = Modifier.fillMaxSize()) {
                drawCircle(
                    color = MaterialTheme.colors.onSurface,
                    radius = 10f
                )
            }
        }
    }
}```

Technically that's in a `DrawScope.()` closure. You need to set a variable before the call to `Canvas` to use it in the closure.
