Hi everybody, i'm pretty new with processing and i really love it but i've some problems S:.

I've to do an excercise that my university teacher gave to me but i cna't pass trought this thing. Essentially, if you look at the screen, i've to fill all the ellipse above the diagonal with a green color and all ellipse below, with a red color.


Now this is what i did:

1. void setup()
   {
     size(350, 450);
     background(253, 212, 145);
     line(30, 400, 30, 50);
     line(30, 400, 300, 400);
     line(30, 400, 300, 30);
   }
   
   
   void draw() {
     int[] posX = {220, 150, 120, 110, 60, 80, 200, 240, 170, 220, 120, 140, 130, 160, 210, 210};
     int[] posY = {350, 180, 220, 320, 280, 200, 310, 290, 130, 240, 280, 260, 340, 320, 200, 270};
     int[] dimensione = {43, 42, 49, 18, 24, 32, 310, 36, 52, 55, 36, 48, 48, 26, 26, 58, 22};
    
     int count= posX.length;
    
     for(int i=0; i<=15;i++){
    
       ellipse(posX[i],posY[i],dimensione[i]/2,dimensione[i]/2);
      
       if(posY[i] > HERE I PUT A VALUE){
         fill(255,155,123);
       }
       else{
        fill(111,144,113);
       }
    
     }
   
   }
