  Turing patterns are fundamental in biophysics, emerging from short-range
activation and long-range inhibition processes. However, their paradigm is
based on diffusive transport processes, which yields Turing patters that are
less sharp than the ones observed in nature. A complete physical description of
why the Turing patterns observed in nature are significantly sharper than
state-of-the-art models remains unknown. Here, we propose a novel solution to
this phenomenon by investigating the role of diffusiophoresis in Turing
patterns. The inclusion of diffusiophoresis enables one to generate patterns of
colloidal particles with significantly finer length scales than the
accompanying chemical patterns. Further, diffusiophoresis enables a robust
degree of control that closely mimics natural patterns observed in species like
the Ornate Boxfish and the Jewel Moray Eel. We present a scaling analysis
indicating that chromatophores, ubiquitous in biological pattern formation, are
likely diffusiophoretic, and that colloidal P\'eclet number controls the
pattern enhancement. This discovery suggests important features of biological
pattern formation can be explained with a universal mechanism that is
quantified straightforwardly from the fundamental physics of colloids and
inspires future exploration of adaptive materials, lab-on-a-chip devices, and
tumorigenesis.
