When xcolor is loaded with the monochrome option, colour is disable for only some, but not all tikz operations.
- Why is this?
- Is it possible to disable colour for all operations?
- is it possible not to disable colour for any operations?
MWE
(Without the monochrome option, everything is drawn in red.)
\documentclass{article}
\usepackage[monochrome]{xcolor}
