11. Special Notice

  • Professional Use: The Color Lab is designed to assist design and development work, but should not be the sole basis for critical design decisions. For important projects (brand launches, product releases, etc.), please conduct thorough visual testing and accessibility validation.

  • Color Display: Different device, browser and display color profiles may cause color display differences. It is recommended to verify color effects on actual target devices, especially in scenarios requiring high color accuracy.

  • Accessibility Standards: WCAG contrast checking is based on standard algorithms, but actual accessibility is also affected by factors such as font size and background complexity. It is recommended to validate with actual user testing.

  • Browser Compatibility: For the best experience, we recommend using the latest versions of modern browsers (Chrome, Firefox, Safari, Edge, etc.). Some advanced features may require specific browser API support.

  • Data Backup: Palette data is stored in browser local storage. Clearing browser data, changing devices or reinstalling browsers will result in data loss. It is recommended to regularly export important palettes for backup.
