How to make variant selector (color, size) button corners sharp in Shopify Horizon theme?

How can you change your color/size selectors from the view below to the more elegant style with sharp corners?

First, let me show you what variant selectors will look like after you make changes in Horizon theme settings.

To achieve this result, follow these steps.

Step 1: Go to themes under Online store and click the Customize button for the Horizon theme.

Step 2: Click on Theme settings, then click on Variant pickers. You can now change the corner radius. For sharp corners, you can set it to 0px. The final step is to save your settings.

This should give your Horizon theme a more expensive and elegant look.

Need swatches on your collection pages too? Rubik Combined Listings links separate products and adds collection-level variant swatches.

The other setting on that same screen

Corner radius is the cosmetic half. The setting sitting right above it is the one that changes what shoppers actually understand: turning those colour squares into real product photos, so someone can see the fabric before clicking. Horizon can show one photo per colour natively.

Where that stops is the gallery. Pick a colour and Horizon still shows every image on the product. Rubik Variant Images narrows the gallery to the selected colour, on Horizon and 350+ other themes, free for one product.
