T3 Adaptive Smoothing Indicator as Scan

Hello Pete, I have a T3 indicator that displays as color changes(red to green), it works great for the chart but I cant seem to build a scan off it. I have been told that is because scans only recognize numbers not colors. How can I change this script to be used in a scan. Below is the code and a screen shot of how it looks when its used.

#hint: indicator: Defines the level of filtering to occur, default is 3
#hint: volumeFactor: Adjusts the amplitude of the feedback added back into the base filter

input indicator = { T1, T2, default T3, T4, T5, T6 };
input price = close;
input period = 10;
input volumeFactor = 0.70;
input displace = 0;
input sign = { default plus, minus };
input Label = No;
input paintbars = No;

script _gd {
input _price = close;
input _period = 10;
input _v = 0.70;
input _sign = { default plus, minus };
def _ema = ExpAverage( _price, _period );
plot _gd = ( _ema * ( 1 + _v ) ) – ( ExpAverage( _ema, _period ) * _v );
}

def _t1 = _gd( price[-displace], period, volumeFactor, sign );
def _t2 = _gd( _t1, period, volumeFactor, sign );
def _t3 = _gd( _t2, period, volumeFactor, sign );
def _t4 = _gd( _t3, period, volumeFactor, sign );
def _t5 = _gd( _t4, period, volumeFactor, sign );
def _t6 = _gd( _t5, period, volumeFactor, sign );

plot T3;
switch( indicator ) {
case T1:
T3 = _t1;
case T2:
T3 = _t2;
case T3:
T3 = _t3;
case T4:
T3 = _t4;
case T5:
T3 = _t5;
case T6:
T3 = _t6;
}

T3.AssignValueColor(if T3 > T3[1] then Color.Green else Color.Red);
T3.HideBubble();

AddLabel(Label, if T3 > T3[1] then ” A ” else ” A “, if T3 > T3[1] then Color.Green else Color.Red);

assignPriceColor(if paintbars and T3 <T3[1] then color.dark_red else if paintbars and T3 > T3[1] then color.dark_green else color.CURRENT);
