Lerping/Fading between multiple colours

Questions & Answers
1

Hi

I have been searching and going through the docs for how to successfully fade from one colour to another but after a few hours of trial and error, have come up still unsure how to achieve this. I thought lerping between colours would be simple enough =(

I have some colliders in the scene and when the player object hits them, it should change the colour of a skysphere I have. At the moment, it changes straight away but I’m after a fade/transition effect so its not so jarring.

I tried the fade script from Unify Wiki:
http://wiki.unity3d.com/index.php?title=Fade
but could not get this working either.
I have been looking at coroutines but am a bit lost with them.

Anyone have some ideas as to how to get this going?
The material colour is passed in from another script.

Thanks

using UnityEngine;
using System.Collections;

public class ChangeSkysphereColour : MonoBehaviour {
	
	public static string materialColour;
	public Color blue = new Color (129.0F,155.0f, 255.0f);
	public Color green = new Color (160.0F,255.0f, 170.0f);
	public Color pink = new Color (253.0F,100.0f, 253.0f);
	public Color yellow = new Color (255.0F,148.0f, 179.0f);
	public Color white = new Color (228.0F,228.0f, 228.0f);
	private Color currentColour;
	
	// Use this for initialization
	void Start () {
		currentColour = yellow;
	}
	
	// Update is called once per frame
	void Update () {
		
		//renderer.material.color = currentColour;
		if(materialColour == "Blue")
		{
		renderer.material.color = Color.Lerp(currentColour,blue, 0.1f);
		currentColour = blue;
		}
		
		if(materialColour == "Green")
		{
		renderer.material.color = Color.Lerp(currentColour,green, 0.1f);
		currentColour = green;
		}
		
		if(materialColour == "Yellow")
		{
		renderer.material.color = Color.Lerp(currentColour,yellow, 0.1f);
		currentColour = yellow;
		}
		
		if(materialColour == "Pink")
		{
		renderer.material.color = Color.Lerp(currentColour,pink, 0.1f);
		currentColour = pink;
		}
		
		if(materialColour == "White")
		{
		renderer.material.color = Color.Lerp(currentColour,white, 0.1f);
		currentColour= white;
		}
		
	}
	
}

Lerp’s last parameter is a number between 0 and 1 representing the current level between the two.

 string lastMaterialColour;
 float t;
// Update is called once per frame
void Update () {
   if(lastMaterialColour != materialColour)
   {
      t= 0; 
      lastMaterialColour = materialColour;
   }
   t += Time.deltaTime;
   //renderer.material.color = currentColour;
   if(materialColour == "Blue")
   {
   renderer.material.color = Color.Lerp(currentColour,blue, t);
   currentColour = blue;
   }
