Different colours of nail polish

topic #26417

As in previous discussions (topic #16124, topic #19192, topic #23929, topic #26417), the coloured nails tags cover both natural colour and nail polish.

Some of the wiki pages need to be updated, though, as they still reference nail polish.

Edit: I've edited the wiki pages myself, copying the wiki page of brown nails for most of them.

The bulk update request #32999 (forum #316672) has been rejected by @yttria.
