Why use yellow instead of white?
Yellow stresses red+green channels differently than white, which activates all three RGB channels.
Yellow screen
Yellow combines red and green channels — useful for warm lighting and detecting defects visible on mixed-channel colors.

Warum einen Yellow-Bildschirm nutzen?
Warm fill light
Yellow provides soft, warm illumination for video calls and photography.
Dual-channel test
Yellow activates red and green subpixels together — catches issues single-channel tests miss.
Banding detection
Gradient-free yellow helps reveal color banding on some panels.
Yellow for mixed-channel testing
Because yellow requires both red and green at full intensity, a faulty green or red subpixel may create visible artifacts.
Warm white points on many monitors lean yellow — compare yellow fullscreen to white to assess color temperature.
