How to add color swatches to the Warehouse theme.

Warehouse is a paid Maestrooo theme, $320 in the Theme Store and at version 7.0.1 (March 13, 2026) as of October 23, 2026. Maestrooo says native color swatches need Warehouse v5 or higher; they're set with Color selector type in the Variant picker block and Color display mode for product cards.

Which route fits Warehouse?

Route 1

Shopify's native swatches.

Native swatch support in Warehouse from version 5.

  1. Update Warehouse to v5 or higher

    Maestrooo says native color swatches need Warehouse v5 or higher, and that they rely on Shopify product categories. Check your version in Online Store > Themes.

  2. 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.

  3. 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.

  4. 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 Warehouse.

  5. Set the color selector to Color swatch

    In the theme editor, open the product page's Product section, select the Variant picker block and set Color selector type to Color swatch.

  6. Show swatches on product cards

    Open Theme settings > Product card and set Color display mode to Swatch.

  7. 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 Warehouse 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.

Warehouse already shows swatches on product pages and product cards, so an app is for extras. Platmart Color Swatches joins separate products into one color picker, Rubik Variant Images & Swatch shows only the chosen color's photos, and GLO Color Swatch Variant Image adds product grouping and a hide-sold-out option.

  1. Duplicate Warehouse first

    In Online Store > Themes, open the menu beside Warehouse 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 draws its own swatches, change Color selector type and Color display mode away from swatches.

  6. Preview a product page and a collection page

    Use the theme editor preview, then a phone, to check both page types in Warehouse. 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.

Route 3

Editing the theme code.

You don't need to edit code for swatches in Warehouse. Warehouse's Variant picker block and Product card settings read native swatches.

Collection pages.

Warehouse shows swatches on product cards with Theme settings > Product card > Color display mode: Swatch.

  1. Set Color display mode to Swatch

    Open Theme settings > Product card and choose Swatch for Color display mode.

  2. Add color filters with swatches (optional)

    The Theme Store lists swatch filters for Warehouse (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.

Swatch problems on Warehouse, 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 Warehouse. In Warehouse, check Color selector type is Color swatch and that the product has a category, since Maestrooo's native swatches lean on it.

  • 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. Maestrooo's older method used 100 x 100 px JPG swatch images; for native swatches, upload the image to the color's entry instead.

  • Out-of-stock variants

    How a sold-out color looks is decided by the variant picker in Warehouse, 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 Warehouse 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.

Warehouse swatch questions.

Which Warehouse version supports native swatches?

Maestrooo says Warehouse v5 or higher. The Theme Store listed Warehouse 7.0.1 from March 13, 2026 on October 23, 2026.

How do I show swatches on Warehouse product cards?

Open Theme settings > Product card and set Color display mode to Swatch.

Does Warehouse suit stores with many colors per product?

Swatches scale well because each color is one entry you reuse across products. For very long color lists, check a product card on a phone after setting Color display mode to Swatch, since many swatches take up room on a small card.

What image size suits Warehouse?

Maestrooo suggests 2400 x 2400 px square product images, or 1800 x 2400 portrait, as JPG. Swatch images can be far smaller.

What if Warehouse's swatch labels look different?

Maestrooo describes the settings in the part of its article about the older method. Look in the Variant picker block for the color selector setting.
