Change GameObject color by C# script

Hi. I have a sample scene like in the picture. What I want is to change the 2nd cube (the one inside GameObject2).
I used:

Code (CSharp):

1. GameObject.Find("Cube").GetComponent<Renderer>().material.color = new Color(0, 204, 102);

But it only change color of the 1st cube.
So is anyway to access to the 2nd cube by code?
Thank you

 

Code (CSharp):

1.  
2.  
3.      foreach(GameObject gameObj in GameObject.FindObjectsOfType<GameObject>())
4.      {
5.          if(gameObj.name == "Cube")
6.          {
7.              gameObj.GetComponent<Renderer>().material.color = new Color(0, 204, 102);
8.          }
9.      }
10.  
11.  

 

Hi raarc,
Thank you for replying to me.
May I ask a further question? If in C# script, I create a public GameObject named Test:

Code (CSharp):

1. public GameObject Test;

Then drag/attach the GameObject1 to Test in Unity.
So in C# script, is there any way for me continue to access, from Test to GameObject2 to Cube, then change its color?
Thank you

 

Code (CSharp):

1. Test.transform.GetChild(0).transform.Find("Cube").GetComponent<Renderer>().material.color = new Color(0, 204, 102);

 

its as simple as adding a second line for the other cube.
just use the name of the other cube insead.

 

For example:
(I'm using this for my game to render colors for all the obstacles)

Code (CSharp):

1. GameObject.Find("obstacle1").GetComponent<Renderer>().material.color = new Color(0, 0, 0);
2. GameObject.Find("obstacle2").GetComponent<Renderer>().material.color = new Color(0, 0, 0);

 

Code (CSharp):

1. var cubeRenderer = GameObject.Find("Cube").GetComponent<Renderer>();
2. cubeRenderer.material.SetColor("_Color", new Color(0, 204, 102));
