Invoking increasingly higher dimension operators to encode novel UV physics in effective gauge and gravity quantum field theories traditionally means working with increasingly more finicky and difficult operators. Can this be simplified? Yes! Color-kinematics duality and its associated double-copy construction has made perturbative gravity calculations as straightforward as perturbative gauge theory. Exploiting this duality, we will find that the scattering amplitude predictions of many higher-derivative operators operators at four-points can be entirely absorbed into the interplay of a small number of scalar building-blocks.
