I have a trigger
#trigger {Exits: (*)} {#sub %ansi(bold,magenta)==>" "%1}

Why doesn't it work?

The syntax for the #SUB command is:
#SUBSTITUTE string [string]

Where the second string is optional. If it is not present, then what #SUB does is substitute the text matched by the last trigger with the first (and only one present) string.

However, if the second string is present, then #SUB creates a new trigger with the pattern set to the first string and the command set to #SUB followed by the second string.

Since in zMUD scripting a space separates command arguments, your #SUB was being evaluated as the latter form. It was creating triggers with pattern %ansi(bold,magenta)==>" and command #SUB "%1.

To prevent this, you must tell zMUD that what comes after the #SUB is all one argument. You do this by enclosing it in braces. Like this:
#SUB {%ansi(bold,magenta)==>" "%1}
