Practical Examples

Perform Color Calibration

Example: Check how your monitor displays these standard colors

1. Click "White" - should be pure white (no color casts)

2. Click "Black" - should be completely black

3. Test Red, Green, Blue - should be pure, bright colors

Result: If colors appear uneven or show discoloration, your monitor may have a calibration issue

Take Relaxation Breaks During Work

Example: Use Blue for a 5-minute relaxation break

1. Set your color to Blue (#0066FF)

2. Click "Enter Fullscreen"

3. Simply gaze at the calming color and breathe deeply

Result: Blue is scientifically known to promote relaxation and concentration
