The joys of fading

Today I've started writing a new class for Penuine that can be used for fading scenes in and out at an arbitrary speed (and the fadeout end colour is also variable). So far the fade in method is working, and I've implemented it in the main menu scene and the level controller. The difficulty with this new class will be not overusing it to the point of it becoming annoying; it's very hard to resist making almost every scene fade in and out simply because it looks cool!
