    First you must name your label:

    then, in code behind do something like this

    if(variable > 0) { MyLabel.BackgroundColor = Xamarin.Forms.Color.Red; }

    This is using code behind. For Forms it's better to use the MVVM design pattern - so you would bind the Color property of the label to a property in the ViewModel. The getter of the ViewModel then returns the appropriate Color depending on the underlying value.
