Call PlotSeries first, then call SetSeriesBarColor to set color for individual bars of your superTrend series.

Thank you Eugene.
I made a small change in the code, and got a big problem. =)
I use KAMA to smooth superTrend.
This code works as expected.

[CODE]
			ATR atr = ATR.Series(Bars, 5);
			CCI cci = CCI.Series(Bars, 50);
			DataSeries superTrend = new DataSeries(Bars, "Super Trend");
			for (int bar = 50; bar < Bars.Count; bar++)
			{
				if(cci[bar] > 0)
				{
					superTrend[bar] = High[bar] + atr[bar];
				}
				else if(cci[bar] < 0)
				{
					superTrend[bar] = Low[bar] - atr[bar];
				}	
			}
			DataSeries kama = KAMA.Series( superTrend, 8 );
			PlotSeries(PricePane, kama, Color.Blue, WealthLab.LineStyle.Solid, 2);
			
			for (int bar = 50; bar < Bars.Count; bar++)
			{
				if(cci[bar] > 0)
				{
					SetSeriesBarColor( bar, kama, Color.Blue );
				}
				else if(cci[bar] < 0)
				{
					SetSeriesBarColor( bar, kama, Color.Red );
				}	
			}
[/CODE]
but when I add another time interval, I can not change the color
[CODE]
			SetScaleDaily();
			DataSeries atrDaily = ATR.Series(Bars, 5);
			DataSeries cciDaily = CCI.Series(Bars, 50);
			DataSeries superTrendDaily = new DataSeries(Bars, "Super Trend");
			
			for (int bar = 50; bar < Bars.Count; bar++)
			{
				if(cciDaily[bar] > 0)
				{
					superTrendDaily[bar] = High[bar] + atrDaily[bar];
				}
				else if(cciDaily[bar] < 0)
				{
					superTrendDaily[bar] = Low[bar] - atrDaily[bar];
				}	
			}
			
			DataSeries kamaDaily = KAMA.Series( superTrendDaily, 8 );
			RestoreScale();
			kamaDaily = Synchronize( kamaDaily );
			PlotSeries(PricePane, kamaDaily, Color.Blue, WealthLab.LineStyle.Solid, 2);
			
			SetScaleDaily();
			for (int bar = 50; bar < Bars.Count; bar++)
			{
				if(cciDaily[bar] > 0)
				{
					SetSeriesBarColor( bar, kamaDaily, Color.Blue );
				}
				else if(cciDaily[bar] < 0)
				{
					SetSeriesBarColor( bar, kamaDaily, Color.Red );
				}	
			}
			RestoreScale();

It's not possible to plot anything in a scale that's different than the underlying chart scale.

In other words, you have to RestoreScale() before you do cosmetic chart operations. See the WealthScript Programming Guide or the Wiki for examples of multi-timeframe operations.
