Black color highlight?

Occasionally, I need to black out portions of text in the document for printing, for example, or to hide sensitive information while using portions of the pdf in slides. I was thinking black color highlight would work well for this purpose. Would it make sense to add this color? Even better - add a color chooser for highlight color?

The problem is a black highlight does not really delete sensitive information it just hides it from plain sight. Actually deleting the content below the highlight is tricky. Clearly, it would be good enough for printing a physical copy but a full redaction tool is more complex.

We have plans to improve color selection we might take that into account. For example it’s a use case to underline in black which is not possible at the moment.
