HDR Color Picker Unity Editor

Hello everyone! I have a question. I want to modify the emission color, but in my custom window it does not come out as I want. I followed the Unity documentation, but the color picker that I want does not come out.

I get the color picker, not the HDR Color

Anybody know how to do it?

using UnityEngine;
using UnityEditor;

public class ColorEditor : EditorWindow
{
    public static ColorEditor window;
    public Material mat;
    public Color colorMat = new Vector4(1, 1, 1, 1);
    public Color emisionMat = new Vector4(0, 0, 0, 1);
    [MenuItem("Window/Color Editor")]
    public static void ShowWindow()
    {
        window = (ColorEditor)EditorWindow.GetWindow(typeof(ColorEditor));
        window.titleContent.text = "Color Editor";
    }
    public void OnGUI()
    {
        EditorGUILayout.LabelField("Color editor", EditorStyles.boldLabel);
        mat = (Material)EditorGUILayout.ObjectField("Select material", mat, typeof(Material), false);
        colorMat = EditorGUILayout.ColorField("Select albedo color:", colorMat);
        emisionMat = EditorGUILayout.ColorField("Select emission color:", emisionMat);
        if(GUILayout.Button("Change values"))
        {
            mat.SetColor("_BaseColor", colorMat);
            mat.SetColor("_EmissionColor", emisionMat);
        }
    }
}

Have you tried using other overloaded variants?

// Example: Includes eyedropper, alpha, and HDR
colorMat = EditorGUILayout.ColorField(new GUIContent("Select albedo color:"), colorMat, true, true, true);

@Eno-Khaon thanks man!
