Color swatch guide

How to add color swatches to the Icon theme.

Icon is a paid theme by We are Underground, $250 in the Theme Store and at version 12.3.2 (June 24, 2026) as of October 23, 2026. The vendor's swatch article covers all of its themes and isn't dated, and it shows the native option's label only in a screenshot, so treat the setting names here as a guide. Icon is one of the themes this domain covered in 2018.

Which route fits Icon?

Route 1

Shopify's native swatches.

  1. Give each product a category

    In Products, open a product and choose the most specific match in the Category field. Categories come from Shopify's Standard Product Taxonomy, and picking one adds that category's attributes to the product as category metafields. You want a category that lists Color (or a color attribute such as Frame color or Band color). If Color is missing under Category metafields, try a narrower category.

  2. Add the colors you sell

    Under Category metafields, open Color and select every color your variants come in. Each color is a reusable entry. You can rename an entry, set its exact hex value or upload a pattern image later in Content > Metaobjects, and the change shows everywhere that entry is used.

  3. Link the Color option to the metafield

    In the Variants section, add an option and pick Color from the suggestions so its values come from the entries you just chose. If the product already has a Color option, open it, use the connect icon beside the option name and choose the Color category metafield. Swatches only appear for options linked this way, so do this on every product you want swatches on in Icon.

  4. Choose swatch as the swatch type

    In the theme editor, open Theme settings > Products and select swatch as the swatch type. We are Underground shows this native option only in a screenshot, so the exact label may differ in your version.

  5. Product cards: not documented

    We are Underground's articles don't document product card swatches for Icon. Look in the collection template's product grid settings; if there's nothing, see Collection pages below.

  6. Check it on a real product page

    Save, then open a product in a private browser window and on your phone. Click each swatch and confirm the price, photo and stock message change with it. If Icon shows plain text buttons instead, go back to the linking step: the option is probably not linked to the Color category metafield yet.

Route 2

A swatch app.

Icon's own swatches cover the product page, but its product card swatches aren't documented. GLO Color Swatch Variant Image and Color Swatch Pug both list collection-page swatches, and OP Color Swatch Variant Images restyles the product-page picker with stock badges.

  1. Duplicate Icon first

    In Online Store > Themes, open the menu beside Icon and choose Duplicate. Set up the app on the copy, preview it, and publish the copy only when the swatches look right. Your live store keeps working while you test.

  2. Install the app and start its trial or free plan

    Install the app from the Shopify App Store and approve the access it asks for. Every app suggested on this page had a free plan, a free listing or a free trial of 7 to 30 days when we checked on October 23, 2026, so you can test before you pay.

  3. Switch on the app embed

    Open the theme editor on your copy (Online Store > Themes, then Customize or Edit theme), click the App embeds icon in the left sidebar, switch on the app's embed and click Save.

  4. Match each color name to a swatch

    In the app's own settings, give each color name a hex value or a small image. Apps read your option values as text, so Navy on one product and Navy Blue on another need two swatches. Tidy the names first and you only set each color once.

  5. Avoid two sets of swatches

    If the app replaces the product-page picker, switch Icon's swatch type off.

  6. Preview a product page and a collection page

    Use the theme editor preview, then a phone, to check both page types in Icon. If the app adds collection-page swatches, click one on a product card and confirm the card's photo or link changes to that color.

Apps that fit Icon

Swatch apps for Icon, from each App Store listing on October 23, 2026
AppFromRatingWhat it does
GLO Color Swatch Variant Image $9.90/month 4.9 (1,906 reviews) A dedicated swatch app whose free plan already covers collection-page swatches and hiding sold-out options; image swatches start on the $9.90 Silver plan.
Color Swatch Pug $6.99/month 4.6 (55 reviews) One $6.99 monthly plan with a 14-day trial for color and pattern swatches on collection and product pages; it isn't Built for Shopify, and its listing still links to this site, which is independent of the publisher.
OP Color Swatch Variant Images $11.90/month 5.0 (802 reviews) Replaces your theme's text picker with color and image swatches plus stock badges; pricing follows your Shopify plan, from $11.90 a month.

Route 3

Editing the theme code.

You don't need to edit code for swatches in Icon. Icon's Theme settings > Products swatch type already reads native swatches.

Collection pages.

We are Underground doesn't document product card swatches for Icon. Swatch filters and apps are the two dependable routes.

  1. Add color filters with swatches (optional)

    The Theme Store lists swatch filters for Icon (checked October 23, 2026). Open the Search & Discovery app, go to Filters > Add filter, choose Color with the type Category metafield, then open Manage values and turn on Include swatch. For patterns, turn on Use images when available so the filter shows each entry's image.

  2. Or add an app for card swatches

    GLO Color Swatch Variant Image and Color Swatch Pug both list collection-page swatches. Test on a duplicate of Icon first.

Swatch problems on Icon, and fixes.

  • Swatches not showing

    Work through three checks in order: the product has a category that includes Color, its Color option is linked to the Color category metafield, and the swatch setting is on in Icon. In Icon, look in Theme settings > Products for the swatch type. If you only see Product variant style and Show custom swatch images, those are the older settings for Icon's own image swatches.

  • Wrong colors

    A native swatch takes its color from the entry in Content > Metaobjects, not from the color's name. Open the entry, correct the hex value and save, and every product linked to it updates at once. If two products show different shades of the same color, they're probably linked to two separate entries, so point both at one.

  • Pattern or image swatches

    Upload a square image to the color's entry. Crop it to the fabric or finish itself rather than a product photo, because at swatch size a busy photo turns into a blur. Multicolor has no preset hex value, so it always needs an image. For Icon's older custom swatches, We are Underground asked for 50 x 50 px PNGs named after the variant; for native swatches, upload to the entry.

  • Out-of-stock variants

    How a sold-out color looks is decided by the variant picker in Icon, so test it: set one color to zero stock and open the product. If you'd rather hide sold-out colors completely, Color Swatch Pug and GLO Color Swatch Variant Image both list that option (checked October 23, 2026).

  • Speed

    Native swatches are drawn by Icon itself, so they add no app script to your pages. A hex swatch costs nothing extra to load; an image swatch adds one small image per color, so keep those files small. The swatch loading speed guide shows how to measure a collection page before and after a change.

Icon swatch questions.

Does Icon support Shopify's native swatches?

Yes. We are Underground's swatch article includes the category-metafield method for its themes, Icon among them. It doesn't name the first Icon version with support.

What were Icon's custom swatch images?

The older method used PNG files of about 50 x 50 px named after each variant, turned on with Product variant style: Swatches and Show custom swatch images.

What product image size suits Icon?

We are Underground suggests 3:4 product images at 1500 x 2000 px, with 900 x 1200 as the minimum (checked October 23, 2026).

Can Icon show swatches on collection pages?

It isn't documented. Check the collection template's product grid settings, then use swatch filters or an app.

Where did the old Color Swatch Pug guide for Icon go?

This page replaces it. The old guide, published on this domain on March 26, 2018, covered a manual install of an earlier version of the app. Today's app uses a theme app embed; the independent setup guide is at /csp-app-setup-guide/.
