Monitoring multiple molecular probes simultaneously establishes their correlations and reveals the holistic mechanism. Current fluorescence imaging, however, is limited to about four colors because of typically circa 100‐nm spectral width. Herein, we show that molecular supracence imparts superior spectral resolution, resolving eight colors in 300‐nm width, about 37.5‐nm per color. A recently discovered light‐molecule interacting phenomenon, supracence only measures molecular emission above its excitation energy due to entanglement between atomic quantum system and electronic quantum system. As such, supracence takes advantage of sharp spectral edge of a single pathway and excitation specificity to produce narrow bands, whereas fluorescence has to deal with multiple pathways spilling out low‐energy long tail, that causes poor resolution. Thus, supracence enables myriad innovative molecular spectroscopy and microscopic imaging with profound impact broadly.
