How can I filter by product color in version 2.0 without using variants?

Guys also if you want different pictures to show up for each color, it’s better to create a Variant meta field called color. and add variations for all the colors you want as preset rules. Then you will see the option come up on the bottom of your variets. Then when you select the filter, the product will appear with the right color picture. You will also need the Search & Discovery app from shopify to format your filter correctly. Im not sure about the color swashes though..
