float x, y;

void setup() {
  size(800, 600);
  strokeWeight(10);
}

void draw() {
  //background(#68CEF5);
  fill(0, 15);
  rect(-50, -50, width + 100, height + 100);
  translate(width/2, height/2);
  rotate(-frameCount/80.0);


  for (int i = 0; i < width; i = i+20) {
    line(i, -i+20, i, i+20);
    rotate(PI/2);

    stroke(#68CEF5);
    point(x, y);
    stroke(255);
    point(-x, -y);
  }
}

I would like to ask you all.

If you wanted to know how to change the Color, you can do so by either using the stroke() or fill() methods depending on what you want to Color. But you should try to be consistent within your Sketch, or at least within one method. And please remember, the General Language of this Forum is english and it is suggested to write in this Language, since Most will look for answers in english and Same goes for People who can answer the questions only if they‘re in english.
