The talk reports on recent progress in amplitude computations
for broad classes of N=2 Maxwell-Einstein and Yang-Mills-Einstein
supergravities, using the framework provided by color/kinematics duality
and the double-copy construction.

After a review of the main theoretical tools, we discuss the extension
of the double-copy construction to a particular infinite family of N=2
Maxwell-Einstein theories in four and five dimensions, the so-called
generic Jordan family of supergravities.

We show that the global symmetries of these theories can easily be
gauged, giving the amplitudes of the corresponding Yang-Mills-Einstein
supergravities. We also discuss how the construction can be modified to
describe spontaneous symmetry breaking. Finally, we present an extension
of the construction that captures an even larger class of N=2
homogeneous supergravities.
