Quick answer
A cyan screen fills your entire display with solid cyan (#00FFFF). Click Fullscreen or press F and every pixel shows the same color, with no toolbars or distractions. Cyan lights green and blue together, so a stuck red subpixel or a missing channel is easy to see. It is also a cool, crisp accent light.

Use cases
A failed green or blue subpixel stands out clearly against cyan.
An aqua glow gives a fresh, modern aesthetic to a desk setup.
Cyan has no red at all, so any red glow indicates a stuck red subpixel.
Check whether cyan leans overly greenish or bluish on different screens.
Cyan Screen guide
Cyan (#00FFFF) is green and blue at full power with red switched off. That makes it a good test for red subpixels stuck on: they appear as white dots on cyan. A blue dot means a dead green subpixel and a green dot a dead blue one. Check the same spot on red to confirm, or see the stuck pixel guide.
Cyan is one of the brightest colors a screen can show, with a cool, clean look. It works as a bright backdrop for product photos, a highlight color for presentations and signs, or a cool accent light. For a calmer cool tone, try a gradient screen or the pastel background.
The display’s green is stronger than its blue. The sRGB color mode or calibration usually brings it back to a balanced cyan.
No. Light blue mixes in some red, while cyan has none. Use the custom color picker to try sky blue or turquoise.
