Here, the preparation of photonic particles that display structural color in both, aqueous suspension and the dry solid state is reported. This is achieved by exploiting the confined self\u2010assembly of a supramolecular comb\u2010like block copolymer (BCP) that microphase separates into a well\u2010ordered lamellar morphology with dimensions that promote a photonic bandgap in the visible range. The comb\u2010like BCP is formed by robust ionic interactions between poly(styrene\u2010<jats:italic>b<\/jats:italic>\u20104\u2010vinyl\u2010pyridine) (PS\u2010<jats:italic>b<\/jats:italic>\u2010P4VP) BCP and dodecylbenzene sulfonic acid (DBSA), which selectively interacts with P4VP blocks. The components are combined in chloroform, and an aqueous emulsion is prepared. Evaporation of the organic solvent leads to the formation of solid microparticles with an onion\u2010like 3D morphology. These photonic pigments display brilliant colors with reflectance spectra featuring pronounced optical bandgaps across the entire visible wavelength range with a peak reflectivity of 80\u201390%.<\/jats:p>","DOI":"10.1002\/marc.202100522","type":"journal-article","created":{"date-parts":[[2021,9,15]],"date-time":"2021-09-15T09:13:05Z","timestamp":1631697185000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Photonic
