How do I cycle through colors in an array, setting the selected color as the colour for an image?

Question

Hi. Firstly, thanks so much to whoever helps.

I am creating an app that lets you train for different sports at home and revolves around drills and the matching colours on the app. In the settings, the player can select a colour to use. The way I would like it to work is that it cycles through the array of colours when you click on the colour in settings. My question is, how do I get the colours to cycles through the array, setting the current colour to the variable colour1?

I have attached some photos.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ColourPicker : MonoBehaviour
 {
     public Color[] colourPalette;
 
     private Color currentSelectedColour;
 
     public Settings settings;
 
     private Color colour1;
 
     void Start()
     {
         colour1 = settings.colour1;
     }
 
     public void ChangeColourOne()][1]
     {
         // Cycle through to the next colour in the array and Set as colour1
     }
 }

  public class ColourPicker : MonoBehaviour
  {
      public Color[] colourPalette;
  
      private Color currentSelectedColour;
  
      public Settings settings;
  
      private Color colour1;
      private int selectedColourIndex = -1;
  
      void Start()
      {
          colour1 = settings.colour1;
      }
  
      public void ChangeColourOne()][1]
      {
          if(colourPalette.Length == 0) return;
 
          selectedColourIndex = (selectedColourIndex + 1) % colourPalette.Length;
          colour1 = colourPalette[selectedColourIndex];
      }
  }

When I try to use your code, all the ChangeColourOne void goes red with an error. The errors go away when I delete ][1] which is after the brackets on the void but the code still doesn't work.

Do you know what might be wrong? Thanks

I blindly copy pasted your code which had this ][1]

Please, define "does not work", it works perfectly fine on my side. colour1 gets changed.

Because Color is a struct, chaging colour1 won't affect settings.colour1`
