How to check if two sprites are the same

I’m making a game about catching falling teacups in a dish bin. One of the mechanics is that the game tells you what color teacup to catch at a certain time, but I’m having difficulty figuring out how to code this. What I want to do is check whether the sprite in a Sprite Renderer game object (the falling teacup) is the same as the sprite in the UI Image game object. If it is the same, the player gets a point.

Right now I have a simple OnCollisionEnter function attached to the dish bin that handles the collision, and my instinct is that another if statement goes inside here. But I don’t know what it should say.

Thanks for any help you’re able to give!

void OnCollisionEnter2D(Collision2D other)
    {
        if (other.gameObject.CompareTag("teacup"))
        {
            Debug.Log("A teacup hit the bin!");
            Destroy(other.gameObject);
            GameManager.instance.IncreaseScore();
        }
    }

okay, I figured it out! Should be:

 void OnCollisionEnter2D(Collision2D other)
    {
        if (other.gameObject.CompareTag("teacup"))
        {
            Debug.Log("A teacup hit the bin!"); //this checks to see whether ANY teacup hit the bin
            
            if (other.gameObject.GetComponent<SpriteRenderer>().sprite ==
                _gameManager.targetTeacupHolder.GetComponent<Image>().sprite) //if the source sprite on the object that has been collided with matches the source sprite on the target image
            {
                Debug.Log("The target kind of teacup hit the bin!");
                Destroy(other.gameObject);
                GameManager.instance.IncreaseScore();
            }

            if (other.gameObject.GetComponent<SpriteRenderer>().sprite !=
                _gameManager.targetTeacupHolder.GetComponent<Image>().sprite)
            {
                Debug.Log("Aww, you messed up");
            }
        }
    }

I think , u could try to compare the Sprite source images.
