What is a blue screen useful for?
A solid color screen helps inspect a display and provides a clean visual surface. It works on computers, phones, tablets, and TVs without downloads.
Blue-channel and cool-tone testing
Blue exposes weak blue subpixels, banding, and cool-tone uniformity issues. It is also a clean background for projection, photography, and ambient light.
