Color Change

[Momentum]

Is there a generic few lines of code I could add to any indicator plot statements that would change the color of the plot of the line when the line was going up and when it was going down?

var vEMA10 = new MAStudy(10, 0, "Close", MAStudy.EXPONENTIAL);
var vLastAlert = -1;

function preMain() {
    setPriceStudy(true);
    setStudyTitle("");
    setCursorLabelName("10ema", 0);
    setDefaultBarStyle(PS_SOLID, 0);
    setDefaultBarFgColor(Color.red, 0);
    setDefaultBarThickness(2, 0);
    setPlotType(PLOTTYPE_LINE, 0);
}

function main() {
         if (
            vEMA10.getValue(MAStudy.MA) > vEMA10.getValue(MAStudy.MA, -1)
        ) onAction1()
         else if (
            vEMA10.getValue(MAStudy.MA) < vEMA10.getValue(MAStudy.MA, -1)
        ) onAction2();
 
    return vEMA10.getValue(MAStudy.MA);
}

    function onAction1() {
        setBarFgColor(Color.RGB(0,0,255));
        vLastAlert = 1;
    }
    function onAction2() {
        setBarFgColor(Color.RGB(255,0,0));
        vLastAlert = 2;
    }
