Visual design
Visual design focuses on app aesthetics through the strategic use of images, colors, fonts, and other elements.
Colors, fonts, icons, illustrations, and many other visual elements have a big influence on your app’s usability. Great apps use strong visual design to heighten the merchant experience.
Fitting into the admin
Anchor link to section titled "Fitting into the admin".Because merchant workflows cross between apps and the Shopify admin, merchants can have an easier time accomplishing their tasks when apps use the same visual design cues as the admin. The easiest way to create a harmonious experience with the Shopify admin is by following our design system, Polaris.
Info
Admin UI extensions blend in seamlessly with the Shopify admin UI. For optimal integration, we recommend that embedded app workflows follow Polaris. Otherwise, the merchant experience across embedded apps and admin UI extensions might break or feel jarring.
Color can provide visual continuity, communicate status information, and give feedback on merchant actions.
Your app exists within the Shopify admin, so you should consider colors that complement the Shopify admin color scheme. Your colors should also respect minimum contrast ratios when used with text or interactive elements.
Do Not
Don't contradict the Color Roles defined by the Polaris design system. In example above, the dark pink affirming action could be misunderstood as red, which is used in the Shopify admin for destructive actions and critical errors.
Must Do
Background-to-text contrast ratio must be at least 4.5:1 to be WCAG AA compliant. Test your ratios using a tool such as WebAIM Contrast Checker.Color roles
Anchor link to section titled "Color roles"The Shopify admin uses certain colors for specific messaging.
These color roles add additional meaning to the interface and reinforce messaging to merchants. Learn more about color roles in the Polaris color guidelines.
Colors like green, yellow, and red have specific roles such as indicating a successful interaction, a warning, or an error. Be careful when using them in your app.
While colors are useful in design, avoid relying on color only to provide context. For alerts like error states, success states, or system warnings, include messaging or iconography that explains what’s happening.
Your app icon acts as the main visual identifier for merchants.
The app icon displays in many touch points, like in the Shopify App Store, on the Apps page in the Shopify admin. Shopify renders your app icon as an SVG into the admin left hand navigation.
Info
For guidance on changing your app icon, go to the App Setup page in the Partner Dashboard.
Tip
App icons will be used on white and light gray backgrounds, so avoid using similar colors that might make your icon illegible. Refer to Polaris style tokens for Shopify admin color values.Specifications

Anchor link to section titled "Typography"Typography is the arrangement of letters in a way that makes reading text easy and comfortable for merchants.
Polaris typography tokens provide a great way to streamline typography.
Type hierarchy
Anchor link to section titled "Type hierarchy"Proper use of typography can improve the app experience. By creating a healthy visual hierarchy between headlines and copy, you’ll improve legibility and consistency with the Shopify admin.
Tip
Typography should create a clear hierarchy between headings and text that’s easily legible by merchants. Whenever possible, the title of the current page should be the largest heading size.
Must Do
Make headings visually distinct from the rest of the text, by being bolder, larger in size, or both. Don’t use underlines that might be mistaken for links.
Do Not
Don't use only color to distinguish a heading to convey hierarchy. This is confusing for merchants who don’t perceive color.Font sizes
Font sizesOur font size specifications apply to the minimum sizes required for legibility in the Shopify admin.
Must Do
Use13px as the minimum size for headings, body text, and text in interactive elements.
Must Do

Icons act as visual aids to help merchants complete tasks. They’re often paired with text to make your app easier to use and to disambiguate certain interactions.
You can save time by using Polaris icons, or create your own by following the Polaris icon guidelines.
Tip
Icons can help merchants better understand the outcome of an action, or help them understand more technical terms that they might not be familiar with.
Do Not
Don't use icons inconsistently in lists and other repeating elements. This makes your app look broken.Illustrations
Anchor link to section titled "Illustrations"Illustrations give your app personality and help merchants understand complex concepts through meaningful visual metaphors.
Following the Polaris illustrations guidelines is a great way to make your app’s illustrations fit nicely with the Shopify admin.
Tip
Keeping a consistent illustration style in your app can strengthen your brand presence and make your app easily recognizable.
