Is there the possibility with
LaTeX of having some element that change if it is printed with colours or in black and white?
I was thinking about the rectangles around links with
hyperref that are visible on the screen but do not appear when the document is printed. I need something similar but that behaves in different ways if is printed in BW or in colours.
The final goal would be to have an image made with
pgfplots with some filling or patterns; when the image is visualized on the screen or is printed with colours I would like to have filling, when instead is printed in BW I would like to have black patterns. This is because the filling with different colours when printed in BW looks very similar and a solution is to use instead different patterns.
