There is no such thing like "Row color" All colors belongs to COLUMNS :-) And if you don't know them nobody can :-))))
You could use a form method to store DynamicBackColor:

*** Somewhere in Form Init:
thisform.Grid1.SetAll([DynamicBackColor],[thisform.SetColumnColor()],[Column])




**** Form SetColumnColor method:
LOCAL lnRGBValue
DO CASE
   CASE SomeCriteria1
        lnRGBValue = RGB(the color you want)
   CASE SomeCriteria2
        lnRGBValue = RGB(the color you want)
OTHERWISE
        lnRGBValue = thisform.Grid1.Columns(thisform.Grid1.ActiveColumn).BackColor
ENDCASE
RETURN lnRGBValue
