# Why is the Falcon Heavy interstage not black?

Falcon Heavy has two side boosters that are essentially standard Falcon 9 lower stage with a nose cone, along with a black interstage, as seen below.

But the renders that SpaceX shows of Falcon Heavy show no black interstage, as seen below.

Why the difference?
