Lime is what happens when green is pushed towards yellow , brighter, more acid, and considerably more visible than either. It sits near the peak of human luminance sensitivity, which is why safety vests are this colour rather than red.
Maximum visibility
The eye is most sensitive to wavelengths around the yellow green boundary, so lime appears brighter than any other colour at the same actual output. On a display that means a lime field is the hardest thing on this site to overlook , useful for a marker screen in a workshop, a visible cue at a live event, or anything that has to register from the corner of someone’s eye.
As an alternative key colour
Lime is not the standard chroma key green, but the choice of key colour is really the choice of a colour nothing in the shot contains. If a subject includes standard chroma green , a logo, a jacket, a piece of equipment , shifting the background to lime can separate them. Software keyers sample whatever colour is present, so what matters is that the background is even and distinct, not that it matches a published value. See the green screen page for the reasoning behind key colours.

Lime screen questions
Why does lime look brighter than white sometimes?
It does not actually exceed white in output, but it can feel close. Human brightness perception peaks in the yellow green region, so a lime field registers as unusually intense for the light it is actually producing. It is the same reason high visibility clothing uses this colour.
Can I use lime for chroma key?
You can, and it is sometimes the better choice , specifically when your subject contains standard chroma green that would otherwise disappear. Keying software samples whatever colour is in the frame, so an even, distinct background matters more than matching a published shade.
