# How to enable Color Comparison on product page?

The "**Color Comparison**" block displays a trigger button that opens a popup modal allowing customers to visually compare different color variants of a product side by side. 

The block only appears when the product has multiple color options defined in the theme's swatch settings. It supports typography customization for the trigger button and custom padding.

## How to enable Color Comparison on product page?

* From your Shopify admin, go to **Online Store** -> **Themes**.
* Find the theme that you want to edit, and then click **Customize**.
* Choose **Products** from the dropdown window.
* Click **Product information** -> add **Perks** block (if not already added).

* By default, the Block Perk will be added to 3 corresponding functional blocks (Size chart, Color Comparison, Ask An  Expert). You can enable or disable them at will by hiding them if you don't want to use them.

  (In this example, we are setting up **Color Comparison**)
