I don't think I've ever used these color tags on danbooru, so tagging them might just be a waste of time. In addition, the backlog will be so long that it will with almost certainty never be complete. Also, what is sheer legwear?

As for what I would find useful, you can do basically every tag under http://danbooru.donmai.us/wiki_pages/33564 that is not under the specific colors header.
