I used something like that once, and yes, they do lift a lot. My natural hair is medium-brown, and the one I used took it strawberry-blonde. So I imagine dark-blonde would be no problem, and the ash should help cut down the risk of any unwanted orangey tones (the one I used wasn't ash, but I've heard it probably would've helped if it had been).
