How do I change the colour a toggle?

Really simple question here but I am unsure of how to use Utility colours with a toggle control.

toggle-balanced for instance

I don’t know if you still need this. But what I did was to target all toggles

.toggle input:checked + .track {
    background-color:#E5D390;
    border-color:#E5D390;
}

this will change the handle color, when the toggle is on

Now that you point that out it looks like we still need to do that. I’ll create an issue, thanks:
