Bollinger Band - Thinkscript question...

I'm having trouble trying to programmatically add a custom colored "cloud"
a/k/a fill to a Bollinger Band study as highlighted below...

FYI, I was able to successfully change the fill the first time. However, after
that, the color would not change/revert no matter what I did...

Any help/assistance would be greatly appreciated. Thanks in advance...

declare upper;

input price = close;
input displace = 0;
input length = 20;

def sDev = stdev(data = price[-displace], length = length);

plot MidLine = Average(data = price[-displace], length = length);
MidLine.Hide();
MidLine.HideBubble();
#MidLine.setStyle(curve.SHORT_DASH);
#MidLine.SetDefaultColor(color.gray);

plot LowerBand = MidLine - 2 * sDev;
LowerBand.SetDefaultColor(color.gray);

plot UpperBand = MidLine + 2 * sDev;
UpperBand.SetDefaultColor(color.gray);

addCloud(LowerBand, UpperBand, color.gray);
#addCloud(LowerBand, UpperBand, color.RED);

@netarchitech Sometimes they work with just one color, I forget the specifics but I think clouds are made from 2 colors. So it would be:

addCloud(LowerBand, UpperBand, color.gray, color.gray);

@rmejia That did the trick! Thanks a million

In the hopes that this will help someone somewhere along the way, here's the final script:

declare upper;

input price = close;
input displace = 0;
input length = 20;

def sDev = stdev(data = price[-displace], length = length);

plot MidLine = Average(data = price[-displace], length = length);
MidLine.SetDefaultColor(color.gray);
MidLine.Hide();
MidLine.HideBubble();

plot LowerBand = MidLine - 2 * sDev;
LowerBand.SetDefaultColor(color.gray);

plot UpperBand = MidLine + 2 * sDev;
UpperBand.SetDefaultColor(color.gray);

addCloud(LowerBand, UpperBand, color.gray, color.gray);
