not fully clear, but here is an example


void setup() {
  size(600, 800);
  background(0, 0, 80);
}

void draw() {
  background(0, 0, 80);

  //Left rec
  if (mouseX<300) {
    fill(150, 100, 0);
  } else {
    fill(0, 0, 0);
  }
  rect(33, 400, 150, 150);

  //Right rec
  if (mouseX>300) {
    fill(255);
  } else {
    fill(0, 0, 0);
  }
  rect(width/2, height/2, 150, 150);
  //
}
//

Thanks for the answer and sorry for not being not so clear in question.
According to the homework, the rectangle must be in center. Implement a
“shadow” for the black rectangle that moves based on the mouse cursor position.
Note that the side of the rectangle closer to the cursor should
remain orange, while the side in shadow should be the same color as the background.

I see

You need to draw shadow first then rectangle I guess

Would look nicer when shadow moves continually

Try

x = map(mouseX, 0, width, -60,60);
