Array indexing problem

Questions & Answers
1

I am trying to get my code to cycle through an array when I press a button and it works for the most part, but some of the colors don’t change. For instance, the order is supposed to be: white, red, orange, yellow, green, blue, purple, pink, and then back to white. The order it actually goes in is: white, red, yellow, yellow, green, blue, pink, pink, and then back to white.

using UnityEngine;
using System.Collections;

public class InputScript : MonoBehaviour {

	public KeyCode UpKey = KeyCode.UpArrow;
	public KeyCode DownKey = KeyCode.DownArrow;
	public KeyCode ChangeColorKey = KeyCode.Backslash;
	SpriteRenderer Sprite;

	int CurrentColor = 0;

	Color[] Colors;

	PongPaddleScript PaddleScript;

	// Use this for initialization
	void Start () {
		PaddleScript = GetComponent<PongPaddleScript>();
		Sprite = GetComponent<SpriteRenderer>();

		Colors = new Color[8];
		// White
		Colors[0] = new Color(255, 255, 255, 255);
		// Red
		Colors[1] = new Color(255, 0, 0, 255);
		// Orange
		Colors[2] = new Color(255, 102, 0, 255);
		// Yellow
		Colors[3] = new Color(255, 255, 0, 255);
		// Green
		Colors[4] = new Color(0, 255, 0, 255);
		// Blue
		Colors[5] = new Color(0, 0, 255, 255);
		// Purple
		Colors[6] = new Color(128, 0, 255, 255);
		// Pink
		Colors[7] = new Color(255, 0, 238, 255);
	}
	
	// Update is called once per frame
	void Update ()
	{
		if(Input.GetKey(UpKey))
		{
			PaddleScript.setDirection(1);
		}
		else if(Input.GetKey(DownKey))
		{
			PaddleScript.setDirection(-1);
		}
		else
		{
			PaddleScript.setDirection(0);
		}

		if(Input.GetKeyDown(ChangeColorKey))
		{
			if(CurrentColor + 1 > Colors.Length - 1)
			{
				CurrentColor = 0;
			}
			else
			{
				CurrentColor += 1;
			}	
			Sprite.color = Colors[CurrentColor];
		}
	}
}

Each color component is a floating point value with a range from
0 to 1.

https://docs.unity3d.com/ScriptReference/Color.html

You can convert the values to a floating point between 0 and 1, or divide the current values with 255.

     // Orange
     //Colors[2] = new Color(255, 102, 0, 255);

     Colors[2] = new Color(255f/255f, 102f/255f, 0f/255f, 255f/255f);
     Colors[2] = new Color(1f, 0.4f, 0f, 1f);
