Black & White

What version? If 2K+, what type of pen styles, color or named?

Make white colour 255 is an easy way of doing this.

Not unless you happen to have white ink and black/dark coloured paper. :-)
With ink you are always working with an absence of any colour AND ink to create white. With light it is always the opposite - where white is the combination of all visible colours.
Unless your paper stock is other than white and you want to print white objects. Problem is - I've never heard of available from anyone! If you have - let the world know!
You can however have very light lines/objects by changing the fill % of the pen/cad colour - say 10 or 20% grey instead of 100% black.
************************************************************ Oxymoron: Black Light

You can have 0% as well. Works quite well, actually.
