Random color doesn't work

[unusualdri]

Hi,
This is the code I have
private val textBuilder = TextDrawable.builder()
private val colorGenerator = ColorGenerator.MATERIAL;

fun String.toTextDrawable() : TextDrawable {
    return textBuilder.buildRound(
            this[0].toString(),
            colorGenerator.randomColor
    )
}

The generated drawable has aways a gray background.

I faced something similar today and wasted 30 minutes looking in the wrong place. Turns out I was using :tint in my XML to color the imageview gray. Remove that property fixed the issue for me.
