Hi, list. I've got a question about color schemes in ConTeXt

What if want to access the entire list of, say, xwi:

for k,v in pairs(xwi_list) do --Supposing xwi_list is contains xwi colors
  (whatever action I want)
end

So far I'm manually setting colors from colo-imp-xwi.mkiv, but I suspect
there's a less manual method. Thank you in advance.

Regards,

Jairo :)
