switch color just for one of instances

Hey, so I've got that quick question, hopefully you could help me out.

I wanted to create coins on a button press,
that will switch colors interchangeably.
So that one would be yellow, the other one - red, the next one - yellow, etc.
but with that code

Code (csharp):

1.  
2. var coin: Transform;
3. var Red = true;
4.  
5. if(Input.GetButtonDown("Jump")){
6.         Instantiate(coin, transform.position, Quaternion.identity);
7.         if(Red){
8.         coin.renderer.material.color = Color.red;
9.          Red = false;
10.         }
11.         else if(!Red){
12.         coin.renderer.material.color = Color.yellow;
13.         Red = true;
14.         }
15.     }

it seems that when I press Jump
ALL of the coins in the scene change color at once.
They all become red,
or yellow, on the next press.

How could I fix it so it behaves as intended?
Thank you in advance.

Rather than changing the original prefab's colour, which is what your script is doing, you need to store the newly created coin in a variable and change its colour.

Code (csharp):

1. var coin : Transform;
2. var red = true;
3.  
4. if (Input.GetButtonDown("Jump")) {
5.     var clone : Transform;
6.     clone = Instantiate(coin, transform.position, Quaternion.identity);
7.    
8.     if (red) {
9.         clone.renderer.material.color = Color.red;
10.     } else {
11.         clone.renderer.material.color = Color.yellow;
12.     }
13.    
14.     red = !red;
15. }
