I would like to paint price candles on a gradient scale using the volume surge value.   I do this manually now and it seems to clog down the system when i create all the individual rules. 

First, price candles are painted white and stay white while VS <1.  
if VS >1 then candles are yellow
if VS >2 then candles are orange
if VS >3 then candles are red
if VS>4 then candles are magenta

I would like to use more shades of the colors thereby being able to identify VS 2.1 vs VS 2.8 (the latter would be a very dark orange, closer to red).  

Im sure there is a way to do this, however I havent had any luck with the RealCode after reading the manual.  

Can someone point me in the right direction?

Click on Volume Surge to edit, then click the Colors tab. Place a check by "Paint with RealCode" then click the Edit link.

Click Indicators/Rules button and select Volume Surge then enter the following code:

'# VS = indicator.VolumeSurge (added when you add VS to the code)

If vs.value > 4 Then
 plotcolor = color.Magenta
Else If vs.value > 3 Then
 plotcolor = color.red
Else If vs.value > 2 Then
 plotcolor = color.Orange
Else If vs.value > 1 Then
 plotcolor = color.Yellow
Else
 plotcolor = color.white
End If
