If she holds it back and only uses short squirts and not much it should work to take the glow of the white off. It is at least a yellow and not smoke like she tried. I used it on a orange calf and I had to use a quit a bit to get it dark enough to match him. The red calf this year I use two colours mixed together to match him, cant remember the colours names, just play around with the white and fawn and I bet it will work.
