What do I do if I want burgundy shoes? Do I decide if I think it's red or purple or blue? Or do I go further and think what the person listing it thought it was? Do I hope the decision went the same way each time, and all shoes have their colour listed? I don't do any of this. I filter by shoes and look with my eyes. Retail search is a poor example because existing retail tagging is poor.
