OnTriggerEnter2D only calling once

void OnTriggerEnter2D (Collider2D any) {

		if (any.tag == "Circle") {
			if (any.gameObject.GetComponent<SpriteRenderer> ().sprite == redState && this.gameObject.GetComponent<SpriteRenderer> ().sprite == redState) {
		
				Debug.Log ("Both Red!");
		
			}
			if (any.gameObject.GetComponent<SpriteRenderer>().sprite == redState && this.gameObject.GetComponent<SpriteRenderer> ().sprite == whiteState) {

				Debug.Log ("White and Red!");

			}
		
		}
	}

This function is calling only once, when two red circles collide again, it doesn’t log, or when is red and another is white…
Why is that?

Use OnTriggerStay to detect collisions every frame.

Turn off “collapse” in the console, or look at the right where the number in the circle tells you how many times each message is repeated.
