About the Blue Screen
Blue sits between the calming end of the spectrum and the display world's favorite tint-check color. A solid blue fill makes it easy to isolate the blue sub-pixel channel, spot color banding, or bathe a room in cool light.
Common uses
- Isolate the blue sub-pixel to check for dead or stuck pixels that don't show up on white
- Reveal color banding or gradient stepping that's hard to see on busy content
- Check for a color tint or cast across the panel, useful after a calibration change
- Use as a calm, cool-toned backdrop for video calls, streaming overlays, or ambient lighting
- Provide a solid blue backdrop for chroma-key style effects when green isn't practical

To check every sub-pixel channel, pair this with the red screen and green screen.
