Hi Tyler,

Here is the formula I reference the  CIMSS/Univ. of Wisc:

def myRGB(chP64,chP86,chP47):  
   green =  0.45*chP64 + 0.45*chP47 + 0.1*chP86
   red = GridUtil.setParamType(chP64,makeRealType("redimage"), 0)
   blue = GridUtil.setParamType(chP47,makeRealType("blueimage"), 0)
   grn = GridUtil.setParamType(green,makeRealType("greenimage"), 0)
    
   return DerivedGridFactory.combineGrids((red,grn,blue),1)

I tested it and the result is pretty good.
