Unity C# Script to change all the ColorPalettes in a scene. (Is only working with the ColorPalettes u3d.as/bFr extension)

ScenePaletteSwitcher.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

namespace MrWhaleGames.ColorPalette
{
  [ExecuteInEditMode]
  public class ScenePaletteSwitcher : MonoBehaviour
  {

    public PaletteData PaletteData;

    public void SwitchAllPalettes()
    {
      Palette[] paletteObjs = GameObject.FindObjectsOfType<Palette> ();

      if (paletteObjs != null) {
        foreach (var item in paletteObjs) {
          item.Data = this.PaletteData;
#if UNITY_EDITOR
          // is need to mark the object as changed
          UnityEditor.EditorUtility.SetDirty (item);
#endif
        }
      }

      PaletteImporter[] paletteImporterObjs = GameObject.FindObjectsOfType<PaletteImporter> ();

      if (paletteImporterObjs != null) {
        foreach (var item in paletteImporterObjs) {
          item.Data = this.PaletteData;
#if UNITY_EDITOR
          // is need to mark the object as changed
          UnityEditor.EditorUtility.SetDirty (item);
#endif
        }
      }

    }


  }
