Add Color Property to Unlit Alpha?

I’m attempting to add a Color field to the existing Unlit/Transparent shader. Here is what I have so far (Compiles, but does not actually modify the color):

Shader "Custom/Unlit Transparent Color"
{
	Properties 
	{
		_Color ("Main Color", COLOR) = (1,1,1,1)
		_MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
	}
	
	SubShader 
	{
		Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent"}
		LOD 100
		
		ZWrite Off
		Blend SrcAlpha OneMinusSrcAlpha 
		
		Material
		{
           	Diffuse [_Color]
		}
		
		Pass
		{			
			Lighting Off
			SetTexture [_MainTex] { combine texture }
		} 

	}
}

Found an answer at the Unify Wiki: unifycommunity.com

Code:

Shader "Unlit/UnlitAlphaWithFade"
{
    Properties
    {
        _Color ("Color Tint", Color) = (1,1,1,1)   
        _MainTex ("Base (RGB) Alpha (A)", 2D) = "white"
    }

    Category
    {
        Lighting Off
        ZWrite Off
                //ZWrite On  // uncomment if you have problems like the sprite disappear in some rotations.
        Cull back
        Blend SrcAlpha OneMinusSrcAlpha
                //AlphaTest Greater 0.001  // uncomment if you have problems like the sprites or 3d text have white quads instead of alpha pixels.
        Tags {Queue=Transparent}

        SubShader
        {

             Pass
             {
                        SetTexture [_MainTex]
                        {
                    ConstantColor [_Color]
                   Combine Texture * constant
                }
            }
        }
    }
}
