What people use a chartreuse screen for
Because Chartreuse is so light, a chartreuse screen doubles as a soft light source: prop a phone or tablet beside you as fill light on a video call, use it as a gentle reading light, or as a backlit surface for tracing.
As a saturated color, chartreuse makes a bold backdrop for product photos, thumbnails and streams, and a strong mood light for a desk or party.
Green screens are best known for chroma-key video: streamers and filmmakers fill a display with pure green to key themselves onto a different background. Green is also the channel the eye is most sensitive to, so a green field is a sensitive test for panel uniformity and stuck pixels, and a softer green makes a calm ambient light.
As a test pattern, a flat chartreuse field makes a dead or stuck pixel jump out, and it exercises the green sub-pixel.
