I created this exact explicit button in my HYPB global button file, didn't
even save the file, activated the button and it displayed the man page
perfectly (Hyperbole 7.0.3b under MacOS).

It looks like you have some personal color settings that are not
recognized, maybe associated with your man page display package.

I think this problem is outside of Hyperbole.  I will close this issue
unless you point to any code reference within Hyperbole that causes such a
problem.

FYI, if you use {C-h h c d} to turn on debug logging for Hyperbole buttons,
then activate one or more buttons and then compose a Hyperbole list mail
message with {C-h h m c}, a log of the buttons and actions that you ran
will be included with your but/issue report.  {C-h h c d} will then toggle
this feature off.
