How to Add Filter by Color in WooCommerce?

If your WooCommerce store sells products in multiple colors, shoppers shouldn’t have to scroll through everything just to find what they like. A color filter lets them narrow results instantly by color, reducing friction and helping them reach a buying decision faster.

In this guide, you’ll learn how to add filter by color in WooCommerce, from setting up color attributes to choosing between built-in widgets, block-based layouts, and AJAX-powered swatches. We’ll also cover SEO best practices and common troubleshooting fixes along the way.

Quick Answer

Color filters in WooCommerce are built on product attributes. Once you create a Color attribute and assign it to your products, you can display it as a filter on any shop or category page.

Here’s the basic process:

1. Go to Products → Attributes and create a Color attribute
2. Add color terms like Black, White, Red, and Blue
3. Assign the correct color to each product
4. Add a Filter Products by Attribute widget or block to your shop page
5. Test the filter on the frontend

How Color Filtering Works in WooCommerce?

Color filters let shoppers narrow down products by color without touching any other filter. Instead of scrolling through everything, they pick a color, and only matching products appear instantly, cutting the browsing process short.

It works by reading the color attribute assigned to each product. When a shopper selects a color, WooCommerce returns only products tagged with that value.

What a color filter does:

• Removes products in unwanted colors immediately
• Helps shoppers decide visually before comparing price or specs
• Reduces scrolling and speeds up purchase decisions
• Works across all product types when attributes are set up correctly

When Color Filters Are Worth Adding?

Color filters are not useful for every store. They work best when appearance is a primary reason shoppers buy, not an afterthought.

A color filter is worth adding when:

• Your store sells products in multiple color variations
• Shoppers browse visually before reading specs or comparing prices
• The same product exists in several colors
• You sell in categories like fashion, home décor, accessories, or lifestyle

What to Set Up Before Adding a Color Filter in WooCommerce?

Before any filter method works, you need two things in place: a color attribute and products assigned to it. Skipping either step is the most common reason color filters appear but return no results.

Step 1: Create a Color Attribute

Go to Products → Attributes and create a new attribute named Color. Once created, add your color terms Black, White, Red, Blue, or whatever variations your store carries. Save the attribute before moving on.

This step defines the color data that the filter will read from.

Step 2: Assign Colors to Your Products

Creating the attribute is not enough. Each product needs a color value assigned to it individually.

• Edit a product
• Go to Product Data → Attributes
• Select the Color attribute
• Assign the correct color value
• Save the product

How to Add Filter by Color in WooCommerce? 5 Proven Methods

WooCommerce gives you multiple ways to add a color filter, like a built-in widget, a block-based setup, and a WooCommerce AJAX product filter for instant visual filtering. The right method depends on your theme type and how visually driven your store is. Here are 5 proven methods to add a color filter to your WooCommerce store.

Method 1: Add a Color Filter Using the Attribute Widget

The attribute widget is WooCommerce’s built-in filtering option. No plugin needed, it works out of the box with classic themes that use a sidebar on shop or category pages.

How to set it up:

• Go to Appearance → Widgets
• Open the Shop Sidebar or product archive sidebar
• Add the Products Filter widget
• Keep Color as the attribute
• Save and test the filter on your shop page

What to keep in mind:

• Displays color names as text, not visual swatches
• Page reloads after every selection
• Only one color can be selected at a time

Method 2: Add a Color Filter Using Blocks

If you’re running a block-based theme, the widget sidebar won’t work. Instead, filters are added directly inside your store templates using the block editor.

How to set it up:

• Go to Appearance → Editor
• Open Templates and select Shop or Product Catalog
• Add the Filter Products by Attribute block
• Select Color as the attribute
• Save and test the filter on your shop page

What to keep in mind:

• Works only with block-based themes
• Functionality is similar to the widget method
• Still displays color names as text, not swatches
• Page reloads after every selection

Method 3: Add a Color Filter Using AJAX (Recommended)

For stores where color drives buying decisions, this method delivers the best experience, instant filtering without page reloads, and visual color swatches instead of plain text.

Step 1: Install the Plugin

Free version:

• Go to Plugins → Add New in your WordPress dashboard
• Search for Dynamic AJAX Product Filters for WooCommerce
• Click Install Now and then Activate

Paid version:

• Purchase the plugin from Plugincy.com
• Download the plugin zip file from your account
• Go to Plugins → Add New → Upload Plugin
• Upload the zip file, click Install Now, and then Activate

Step 2: Enable the Color Attribute Filter

• Go to Product Filters → Form Manage
• Find the Show Attributes option and toggle it on

Step 3: Style the Color Filter

• Go to Product Filters → Form Style
• Select Color from the attribute dropdown
• Choose the color filter style and how you want to display

Step 4: Display the Filter on Your Shop Page

• Go to the page where you want the filter to appear
• Add the shortcode [plugincy_filters] to display the filter
• Optionally add [products] alongside it to display products

Step 5: Save Changes

• Click Save Changes to apply everything

Method 4: Add a Color Filter Using Your Theme’s Built-in Filter

Some WooCommerce themes come with native filtering built in. Themes like Flatsome, Astra, and OceanWP include their own filter options that support color attributes out of the box. If your theme has this, it is worth checking before reaching for a plugin.

How to check if your theme supports it:

• Go to Appearance → Customize
• Look for a Shop, Product Archive, or WooCommerce section
• Check if attribute-based or color filtering is listed as an option

How to enable it:

• Enable the filter option from your theme’s customizer
• Select Color as the attribute to filter by
• Choose where the filter appears: sidebar, top bar, or off-canvas
• Save and test on your shop page

What to keep in mind:

• Works only if your theme natively supports attribute filtering
• Customization options and swatch support vary by theme
• No additional plugin needed if your theme covers it fully

Method 5: Add a Color Filter Using Custom Code

If you prefer full control over how the color filter works without relying on a plugin or theme, you can build it using custom code. This method is best suited for developers who are comfortable working with WordPress hooks, WooCommerce functions, and PHP queries.

How it works:

WooCommerce stores color as a product attribute. Using a custom tax_query, you can filter products by their color attribute value and display only matching results on the shop or category page.

Basic setup steps:

• Add a color filter form to your shop page template using custom HTML
• Use $_GET to capture the selected color value from the URL
• Pass the value into a tax_query inside a custom WP_Query or hook into woocommerce_product_query
• Display the filtered results on the page

Basic code example:

php

add_action( ‘woocommerce_product_query’, ‘filter_products_by_color’ );

function filter_products_by_color( $q ) {

if ( ! empty( $_GET[‘color’] ) ) {

$tax_query = (array) $q->get( ‘tax_query’ );

$tax_query[] = array(

‘taxonomy’ => ‘pa_color’,

‘field’ => ‘slug’,

‘terms’ => sanitize_text_field( $_GET[‘color’] ),

);

$q->set( ‘tax_query’, $tax_query );

}

}

Which Method Should You Use?

The right method depends on three things: your theme type, your store’s visual needs, and how much control you want over the experience. Here’s a quick breakdown to help you decide.

How to Make Your Color Filter Look Better?

Setting up a color filter is one thing; making it look good and feel intuitive is another. A well-designed filter keeps shoppers engaged and reduces the chance they leave without finding what they want. Here’s how to make your color filtering look better.

Use Color Swatches Instead of Text Labels

• Swatches let shoppers identify colors instantly without reading
• Visual recognition is faster than text, especially on mobile

Keep Your Color Options Focused

• Only display colors that are actually in stock
• Too many options overwhelm shoppers and slow down decisions

Show Product Count Next to Each Color

• Helps shoppers know how many options are available before clicking
• Reduces dead-end filtering experiences

Combine It With Other Filters

• Pairing your color filter with the ability to add filter by categories in WooCommerce gives shoppers a more complete browsing experience
• More filter options mean shoppers can narrow results from multiple angles

Use AJAX Filtering to Remove Page Reloads

• Instant results feel smoother and more responsive
• Shoppers are more likely to try multiple color combinations when there is no reload delay

Keep the Filter Visible Without Scrolling

• If the filter is buried below the fold, shoppers won’t find it
• Sticky sidebar filters work well for longer product lists

Common Color Filter Problems and How to Fix Them

Most color filter issues are not complicated; they usually come down to a missing setup step or a placement issue. Whether you are using WooCommerce product filter for color, price, or any other attribute, these problems tend to follow the same pattern. Here are the most common ones and how to fix them quickly.

Frequently Asked Questions About Color Filters in WooCommerce

Here are answers to the most common questions about color filtering in WooCommerce, covering edge cases and details not fully addressed in the guide above.

Can I Add a Color Filter Without a Plugin?

Yes. WooCommerce includes a built-in Filter Products by Attribute widget and block that work without any plugin. However, these options display color names as text only and do not support swatches or instant AJAX filtering.

Does a Color Filter Work With Variable Products?

Yes, as long as color attributes are assigned correctly to the product variations. If a variation is missing its color value, it will not appear in filtered results even if the parent product has a color assigned.

Can Shoppers Select More Than One Color at a Time?

This depends on the method you use. The built-in widget only allows one color selection at a time. AJAX-based filter plugins support multi-color selection, letting shoppers browse across several colors simultaneously.

Will Adding a Color Filter Slow Down My Store?

A well-configured color filter should not noticeably affect page speed. AJAX-based filters can actually improve perceived performance since product results update without a full page reload. Poor performance is usually caused by unoptimized themes or too many conflicting plugins.

Do Color Filters Work on Mobile?

Yes, but the experience varies by method. Text-based filters from the built-in widget can feel small and hard to tap on mobile. AJAX-based filters with visual swatches are significantly easier to use on smaller screens and are the better choice for stores with high mobile traffic.

Final Thoughts

Color filtering is one of those small additions that makes a big difference in how shoppers experience your store. When done right, it removes friction, speeds up decisions, and helps buyers find exactly what they are looking for without unnecessary scrolling.

Learning how to add filter by color in WooCommerce does not have to be complicated. Whether you go with the built-in widget for a simple setup, a block-based approach for an FSE theme, or an AJAX-powered filter for a more visual experience, the right method is the one that matches your store’s needs and your shoppers’ expectations.
