This post is a sincere suggestion to developing thingiverse. Printing stuff is cool but multi-extruder kit (indirectly multi-color filament) usage is still rare and most of people use most common colors as black-white-blue etc... I thought designs in your site could be categorized for their best color option as well. For instance, I've made a search for a crow and its obvious best color is black. What I want to point out, I'd be happy to see a bar where I can search for "best things for red(any color) filament". Bests.
