Hello guys !

I was drawing some ellipses and a rectangle to create an island and i would like to pick up colors that i choose in rgb  to fill the island, the sea and the ombrel with the appropriate colors but when  my mouse is on the button, all the elements become a same color, why ? Can you help me please ?
and i was wondering how can i make my ellipse (the island) remain yellow when my mouse is pressed, i tried "if mousepressed" , of course, it didn t work but i think i lack  something ...

Thanks for your precious help : )

This is my code :


color sable,mer,ombrelle;
void setup (){
  size (500,250);
  smooth();
  background(7,207,240);
  colorMode(RGB);
sable = color (224,203,168);// rgb
mer = color (8,150,190);
ombrelle = color (255,0,0);

}


void draw(){
  color souris = get(mouseX,mouseY); // remplit forme entiere
  noStroke();
fill(sable);
rect(0,0,20,20);
fill(mer);
rect(0,20,20,20);
fill (ombrelle);
rect(0,40,20,20);

//sea
fill(souris);
noStroke();
rect(0,100,1080,650);

// îsland
fill(souris);
noStroke();
ellipse (50,200,1000,150);

//ombrelle
   noStroke();
   fill (souris);
   ellipse (150,100,200,90);
   //dessus baton
   stroke (100,50,30);
   fill (0,50,50);
   rect (150,70,10,22);
   //baton
   stroke (100,50,30);
   fill (0,50,50);
   rect (150,145,10,70);

}
