Effect: Gradually increasing color on interaction and restore to original

[IAFahim]

How to create the effect where: If players press a button it becomes a bit dark, and the more they press, the darker it gets, and after the player stops clicking for a duration the button turns back to original color.

Something like this:

[SerializeField] Image buttonImage;
Sequence colorAnimation;

void Update() {
    if (Input.GetMouseButtonDown(0)) {
        colorAnimation.Stop();
        colorAnimation = Sequence.Create(Tween.Color(buttonImage, Color.black, 1));
    }
    if (Input.GetMouseButtonUp(0)) {
        colorAnimation.Stop();
        colorAnimation = Sequence.Create()
            .ChainDelay(0.5f)
            .Chain(Tween.Color(buttonImage, Color.white, 1));
    }
}
