How to change transparency of objects not selected?

I have a patch three style game. I want to change the transparency of all the nodes that don't match a selected color. So imagine you select purple, everything not purple I want to dim.

protected void matchByLinkedList()
{
    List<Node> nodes = new List<Node>();  //makes a new list of nodes when touched
    Debug.Log(List<Node>);
    LinkedListNode<Node> linkedListNode = linkedList.First; //creates a list of the selected nodes.
    int element = linkedListNode.Value.element;  //This gets the value of the selected Node's element

}

Above is what I am using to make the selections. element is a field I have put on the prefab to identify the color. Red = 1, Purple = 2 etc..

Do I need to do a foreach that doesn't equal element (1) edit transform? I feel like I am missing some steps in between in my thought process.

I don't really understand how I am supple to make a list of all items that don't match and then set the transform on those.

Thanks for the help.

There are many ways to do this, generally it's better to avoid loops as much as possible. you can achieve this by having a static Node field in your Node class and compare InstanceId of any node with it.

public class Node : MonoBehaviour{

internal static Node SelectedNode;

//call this somehow
public void OnSelect(){
  SelectedNode = this;
}

void Update(){
  if(this.GetInstanceID() == SelectedNode.GetInstanceID())
  {
    //dim this
  }
}
}

edit

make sure you don't compare the InstanceId of a GameObject with InstanceId of a Component or so. both Objects must have the same type or otherwise it always returns false.
