BLACK MODE ???

 

Black space ???
I've read the beginner's instructions on your website (Ohjemsta), and there are some beginner's instructions there, but before I even get to that I'd like to change the black space to white? I'm used to drawing with black lines on a white background?? Why aren't there instructions for such a simple beginner's thing right at the beginning ????????

So my problem is the black workspace as a whole? Why can this be so difficult to figure out??
