By engineering and manipulating quantum entanglement between incoming photons and experimental apparatus, we construct single-photon detectors which cannot distinguish between photons of very different wavelengths. These color-erasure detectors enable a new kind of intensity interferometry, with potential applications in microscopy and astronomy. In this work, we demonstrate chromatic interferometry experimentally, observing robust interference using both coherent and incoherent photon sources.
