You get a list of defined color names in 'xwi' with:
attributes.colors.setlist("xwi")
Nice, it works! I note the first method only works when \usecolors[xwi]
is present; otherwise, it prints an interesting "themaintextcolor".
Here is a nostalgic mkii accessor for such a list (color support is a
real old feature and conceptually hasn't changed that much):
\def\WhateverActionIWant#1{#1\par}
\settrue\collectcolorsinlist \setupcolor[xwi]
\processcommacommand[\colorlist]\WhateverActionIWant
but you probably don't want to catch up on that.
It doesn't work in Mark IV (\colorlist is undefined). Maybe I'm too
young, but Mark II was already frozen when I was a teenager, so I'm not
sure I want to try it now. Thanks, Hans!
It's low level mkii, never meant for usage outside core code (in this
case in mkii it is used for typesetting color overviews); mkiv still has
the same high level commands but different low level ... nothing to
worry about. The only high level commands that were dropped in mkiv were
those dealing with obsolete technologies, encodings and such)
