1. A composition comprising:
a peptide self-assembly comprising a plurality of a peptide, the peptide having a packing sequence that includes no more than three amino acids,
wherein the peptide further includes melanin derived from oxidation of tyrosine residues, the melanin providing an aromatic and conjugated system to the peptide self-assembly,
wherein the packing sequence determines size, compacity, and morphology of the peptide self-assembly, and
wherein the composition has a color provided by the aromatic and conjugated system of the peptide self-assembly.
