Morphology

redline = red + line (semi-transparent) = red + line

Built from 'red' + 'line' used figuratively to mean a non-negotiable boundary; the metaphorical extension is not fully predictable from the parts alone.

Etymology

Redline comes from the idea of drawing a red line to show a 'limit' you must not cross, like a border on a map or a firm demand in talks. So a redline is a boundary that ends negotiations if it is crossed.
