What people use a royal blue screen for
As a saturated color, royal blue makes a bold backdrop for product photos, thumbnails and streams, and a strong mood light for a desk or party.
Blue screens are the standard for bias lighting — a dim blue or blue-white glow placed behind a monitor or TV lowers the perceived contrast of the room and eases eye strain during long sessions. Blue is also the reference for checking the blue sub-pixels of a panel, a favourite for "blue screen" jokes, and a moody backdrop for photography and streams.
As a test pattern, a flat royal blue field makes a dead or stuck pixel jump out, and it exercises the blue sub-pixel.
