blue sky

Clear day's ceiling

Blue sky as an adjective describes something theoretical, optimistic, or unconstrained by practical limitations: blue-sky thinking, blue-sky research.

It suggests creative freedom unbound by immediate application or feasibility.

In finance, blue-sky laws regulate securities to protect investors from fraud—from the idea of selling nothing but blue sky.
