Reply To: Color as Category

Hello,

There is no automated way. If you show the Product categories in the widget, these color categories will also be shown.

One more way: assign tags of colors you need to each product.
Next, create a layout similar to Product Categories using row and columns and then by means of promo banner show the tag pages where all the products related to the color will be shown

The sample of banners are here https://woodmart.xtemos.com/banners/
