Surface Forms

blue-green positive

Morphology

blue-green = blue + green (semi-transparent) = blue + green

The components are the colour labels 'blue' and 'green', but the sense refers to a domain-specific deployment strategy named metaphorically, so the full meaning is not directly deducible from the colours alone.

Etymology

Blue-green in computing comes from using two identical environments called blue and green, so you can switch all user traffic from one to the other; imagine two identical rooms painted different colors to see why this lets teams release changes safely and roll back quickly.
