Non-destructive analysis by means of portable X-ray flourescence (pXRF) and Raman spectroscopy of color
traces on sculptures and architectural parts from the Delphi Museum, Phokis, Greece, are presented. These
sculptures and architectural parts are dated to the Archaic period (7th – 6th c. B.C.). The main question to be
answered is the mineral/pigment used for each part and therefore to reconstruct the color palette of the
artists. For this research, sixteen archaeological exhibits of the Delphi museum were analyzed with two
different spectroscopies, and the white, red, black, yellow and blue pigments were identified.
