How to clear the background color in hatching

[fsztuczny]

Hello

I noticed that from the GUI it is possible to set the background colour to None. From .Net API BackgroundColor has the flag IsNone = true set. I am guessing that the colour should be assigned with this flag set. How do I create such a colour?

I found a solution through experimentation. It works:

hatch.BackgroundColor = Color.FromEntityColor( new EntityColor( ColorMethod.None ) );
