Thanks,I was using wrong rgb codes.I just did a print of the cell font color and it directed me to the right values.I see Moken has advised the same correction.
Var1 = ""
Var2 = ""
if source_sheet['C11'].value == None:
Var1 = "No Data"
elif source_sheet['C11'].font.color.rgb == "FF92D050":
Var1 = "Green"
elif source_sheet['C11'].font.color.rgb == "FFFF0000":
Var1 = "Red"
print(Var1)
