Coloured layers

In a multi layered application one is bound to travel up and down and up again through the layers. It is usually not hard to keep track of where one is; just read the contents of the methods or check the namespace in suitable textbox.

But wouldn't it be nice to have an extra signal? I am thinking of changing the colour of the background or frames or something. Not from red to green but something more subtle. Ridiculous thought? That is what I thought too when I first encountered coloured source code. "colouritis" whas my response. Today I cannot live without it and wouldn't mind using different fonts the same way.

Ok, ok. "cannot live without" was an aggravation.
