Detect color transition and banding issues
This tool displays smooth color gradients to help you detect if your display can show smooth color transitions without banding artifacts.

Observe if color transitions are smooth and natural
Switch between different gradient types for comprehensive testing
Visible bands or steps in the gradient instead of smooth transitions. This is usually caused by insufficient color depth (e.g., 6-bit panels) or driver issues.
Colors in certain areas noticeably deviate from the normal gradient path. This may indicate inaccurate display color calibration.
Ideally, gradients should be very smooth with no visible boundaries. 8-bit or higher color depth displays typically perform better.
Bit depth affects how many colors a display can show. 8-bit panels can display about 16.7 million colors, while 6-bit panels only about 260,000.
High-quality displays should show very smooth gradients with barely visible banding. If you see obvious bands, consider upgrading your display or adjusting settings.
Note: Browser and operating system color management also affects test results. Testing under optimal display settings is recommended.
