First of all you need to use namespace UnityEngine.UI then assign Image and get its color, alpha etc...

Example : Attach this script to your Image gameobject :

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Test : MonoBehaviour {
 
     public Image image;
     public Color imageColorToBeUsed = Color.green;
     public float currentImageColorAlpha = 0.5f;
 
     // Use this for initialization
     void Start () {
         image = GetComponent<Image> ();
         //Get the alpha value of Color
         currentImageColorAlpha = image.color.a;
         //Assign Color
         image.color = imageColorToBeUsed;
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 }

Hope this will help :)

  using UnityEngine;
  using System.Collections;
  using UnityEngine.UI;
  
  public class Test : MonoBehaviour {
  
      public Image myimage;
      
      void Update () {
           myImage.CrossFadeAlpha(1.0f, 1.0f, true);//CrossFadeAlpha(Alpha, Time, Ignore time scale)
      }
  }
