[NTG-context] Iterate over color scheme in ConTeXt/Lua

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 :)
