How to Change the Color Scheme in Shopify Horizon Theme

Horizon's colors are controlled by reusable color schemes, not one-off settings per section — change a scheme once and every section using it updates together.

Steps

1. In your Shopify admin, go to Online Store > Themes and click Customize on Horizon.
2. Click Theme settings (the paintbrush icon) at the bottom of the left panel.
3. Select Colors.
4. Click into any scheme to edit its background, text, button, and border colors.
5. Add a new scheme with Add scheme if you need an extra combination for a specific section or block.
6. Click Save.

Per-section overrides

Assign schemes to individual sections — and, since Horizon supports nested blocks, to individual blocks within a section too — from that section or block's own settings. You don't need code or an app for basic palette changes.
