OBJ_RECTANGLE Color Problem!

[fly7680]

Hello, I have a little problem with superimposed color rectangles. Only when these objects are overlapped area becomes black, how can I solve?

// 1° Rectangle
ObjectCreate("Zon1",OBJ_RECTANGLE,0,Time[0],price1,iTime(0,TF,index1),iHigh(0,TF,index1));
ObjectSet   ("Zon1",OBJPROP_COLOR,Brown); 

// 2° Rectangle
ObjectCreate("Zon2",OBJ_RECTANGLE,0,Time[0],price2,iTime(0,TF,index2),iHigh(0,TF,index2));
ObjectSet   ("Zon2",OBJPROP_COLOR,Brown); 

// 3° Rectangle
ObjectCreate("Zon3",OBJ_RECTANGLE,0,Time[0],price3,iTime(0,TF,index3),iHigh(0,TF,index3));
ObjectSet   ("Zon3",OBJPROP_COLOR,Brown);
