A consistent picture of the Au+Au and D+Au, {radical}(s) = 200 A GeV measurements at RHIC obtained with the PHENIX, STAR, PHOBOS and BRAHMS detectors was previously developed with the simulation LUCIFER. The approach was modeled on the early production of a fluid of pre-hadrons after the completion of an initial phase of high energy interactions. A successful description of both measured ''jet'' suppression and elliptical flow is obtained with a key element being the early production of pre-mesons which are relatively strongly interacting. The synthesis of these two signals in a common description puts in doubt the likelihood of direct hadronic observation of the colored phase which, for appreciably hard partons, lasts only a short interval {approx}t{sub p}, while the time for pre-mesons to hadronise t{sub f} is in general considerably longer.
