Summary display of the experimental approach comprising resonance and non-resonance Raman micro-spectroscopy, HR-SEM, EDX, XRD of blue, red, white and green exoskeleton of C. sapidus and C. aestuarii crabs in native form. Blue shells turning red when cooked or solvent extracted is molecularly illustrated by Raman spectroscopy.
