Find the color of your listings!
The Colormatic is a nifty little tool that can show you which color Etsy thinks a listing is. It's this color value which is used for the Color Search feature. Unfortunately, due to a bug in Etsy's image color evaluation routine, which is run at image upload, most listings appear to be white to Etsy. If you want to know what color a listing is to Etsy's eyes, simply enter its ID and press Get Color!, after which a box with the item's color will appear.
