Particles (Legacy) wont render

Hi guys, I am a Unity Noob.

So I was following a tutroial to learn somthing, when the tutorial particle system was outdated compared to unity 4 that uses Particles (Legacy). So I tried to figure it out with the new system. All went well until I made a script that changes colour of the particles.

The problem is that when I change the colours, the particles are no longer visible, Then I also discovered that if I change less then 4 colours (out of 5) the particles are still visibole.

Can you please tell me what I am doing wrong?

Thanks a lot

Java code used:

 #pragma strict
 
 public var myColors:Color[];
 
     function Start () {
         
         var particleAnimator : ParticleAnimator = GetComponent(ParticleAnimator);
         var modifiedColors : Color[] = particleAnimator.colorAnimation;
         modifiedColors = myColors;
         particleAnimator.colorAnimation = modifiedColors;
     }
