  From the perspective of effective field theory (EFT), Wilson coefficients of
the low energy theory are determined by integrating out modes of the full
ultraviolet (UV) theory. The spectrum can be in principle resummed if one has
access to all available infrared (IR) coefficients at low energies. In this
work we show that there exists a general class of consistent massive resonance
double-copy (CMRDC) models where UV massive residues are reconstructed through
double-copy consistency conditions between the IR Wilson coefficients of the
full EFT expansion. Through a color-dual bootstrap, we find surprisingly that
double-copy consistency alone introduces the kinematic factors of CMRDC models
that soften high energy behavior by exponentiating color-dual contacts. This
bootstrap suggests that our massive resonance paradigm is an inevitable
consequence of the duality between color and kinematics, thereby providing a
path towards emergent UV structure directly from the IR. We then demonstrate
how CMRDC models can capture a spectrum of massive modes compatible with
general multiplicity, and use Pad\'{e} extrapolation to solve the inverse
problem of identifying massive UV resonance from a small number of IR Wilson
coefficients.
