const int bluePin = 9;
int counter = 0;

void setup() {
  pinMode(buttonPin, INPUT);
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(bluePin, OUTPUT);
}

void loop() {
  int buttonState;
  buttonState = digitalRead(buttonPin);
  
  if (buttonState == LOW) {
    counter++;
    delay(150);
  }
  
  else if (counter == 0) {
    digitalWrite(red, LOW);
    digitalWrite(green, LOW);
    digitalWrite(blue, LOW);
  }

Looking back on my childhood, I was happy when I was making something and I was proud of myself. "Making is instinct!"
