Fading textures in/out (C#)

So I made this intro video here but since I’m using Unity Free, I can’t actually have the video play in-game.
So I have no choice but to remake it in Unity.
I can find ways to fade the textures easily in Javascript, but I can’t seem to find any way to do it in C#.

I’m using an IEnumerator to make sure the images display at the right times.
