Answer 1

You can change the alpha channel from the Color attribute:

Text(text = funfact, fontSize = 18.sp, color = Color.White.copy(alpha = 0.5f))

Answer 2

You can also use the alpha modifier:

Text(
    text = funfact,
    modifier = Modifier.alpha(0.5f),
    fontSize = 18.sp,
    color = Color.White,
)
