Change AC menu font color through Action

FMStudio

Hi there,
I've successfully created a custom action to change a menu element font and font size but I can't succeed in changing font color.
This is my script:

using UnityEngine;

#if UNITY_EDITOR
using UnityEditor;
#endif

namespace AC
{
    [System.Serializable]
    public class ActionChangeFontColor : Action
    {
        // Declare variables here
        public string MenuName;
        public string ElementName;
        public Color MyFontColor;

        public ActionChangeFontColor()
        {
            this.isDisplayed = true;
            category = ActionCategory.Menu;
            title = "Change Menu Font Color";
            description = "Change Menu Font color";
        }
        override public float Run()
        {
            AC.PlayerMenus.GetElementWithName(MenuName, ElementName).fontColor = MyFontColor;
            return 0f;
        }
#if UNITY_EDITOR

        override public void ShowGUI()
        {
            // Action-specific Inspector GUI code here
            MenuName = EditorGUILayout.TextField("Menu name:", MenuName);
            ElementName = EditorGUILayout.TextField("Element name:", ElementName);
            MyFontColor = EditorGUILayout.ColorField("Font Color:", MyFontColor);

            AfterRunningOption();
        }
#endif
    }
}

no matter which color I choose, the text stops appearing.
What am I doing wrong?
Thanks!

The code looks correct - does the new colour have its alpha set to 1?

I'm an idiot...
Thanks and sorry for bothering!
