clrNONE в тестере

Почему в тестере mql4 этот код возвращает false? Как можно указать пустой цвет и для тестера и не тестера?

#property strict
#property indicator_chart_window
color input a = clrNONE;

//| Custom indicator initialization function                         |

   return(INIT_SUCCEEDED);
}

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
  {
     Print(a == clrNONE);
     
     return(rates_total);
  }
