Description

The WordPress.com Site Editor color picker fails to display any visible colors when Windows High Contrast mode is enabled. Color swatches appear as empty/blank circles or squares, making it impossible for users to select colors visually.

Step-by-step reproduction instructions

1. Enable Windows High Contrast mode (e.g., Desert theme)

2. Log in to WordPress.com and navigate to Site Editor on a site with a Block theme

3. Go to Appearance → Editor → Styles → Colors → Button → Background

4. Observe the color picker/color swatches
