Fade in with CrossFadeAlpha

So I think I reversed the meanings, FadeOut being "fade out the players vision" and the opposite for FadeIn. Now, I can make the screen fade from black to normal but not in the other direction. Is there anything wrong with my script or do I just not understand CrossFadeAlpha? The debug log suggests that all parts are being called in the correct order. I'm pretty sure it's a simple mistake somewhere but I cannot figure out what.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class FadeScreen : MonoBehaviour {
 
     private Image Image;
     Color color = Color.black;
 
     // Use this for initialization
     void Start () {
         Image = gameObject.GetComponentInChildren<Image>();
         Disable();
     }
     
     // Update is called once per frame
     void Update () {
     }
 
     public void Disable()
     {
         Debug.Log("Disabling Fade Image");
         Image.enabled = false;
     }
 
     public void Enable()
     {
         Debug.Log("Enabling Fade Image");
         Image.enabled = true;
     }
 
     public void FadeIn(int seconds)
     {
         Debug.Log("FadeIn called");
 
         Enable();
         color.a = 1;
         Image.color = color;
 
         Image.CrossFadeAlpha(0, seconds, false);
     }
 
     public void FadeOut(int seconds)
     {
         Debug.Log("FadeOut called");
 
         Enable();
         color.a = 0f;
         Image.color = color;
 
         Image.CrossFadeAlpha(1, seconds, false);
     }
 }
