**What should have happened instead?**:
The quote card with an image has a `dominant-color-hex` background color. The text is legible and has a `dominant-color-contrasting` color.
**Software version** (on `Special:Version` page; skip for WMF-hosted wikis like Wikipedia):
**Other information** (browser name/version, screenshots, etc.):
- Verified on Firefox browser on an iOS device with light/dark appearance settings.
- Verified Minerva theme settings are unrelated. Switching Minerva light/dark theme does not affect the card element's background color. It affects other dialog elements: `scrollable-container`, `dialog__header`, and `dialog__footer`.
- For testing, try BrowserStack (limited access/seats) or a local server on a real mobile device.
