This article intends to demonstrate MOLAB’s multi-technique in-situ noninvasive approach as applied to the study of the materials found in Mondrian’s painting, <i>Victory Boogie Woogie</i>, conserved at the Gemeentemuseum, The Hague. The study was carried out using five portable spectroscopic techniques; x-ray fluorescence, mid-infrared reflectance spectroscopy, near infrared reflectance spectroscopy, UV-vis spectroscopy in absorption and emission modes and fluorescence imaging, allowing for the identification of the pigments employed by Mondrian in his last unfinished masterpiece. Signature key elements belonging to each of the colours employed by Mondrian along with the clean lines and restricted palette of the artist allowed for a greater elaboration of the build-up of the work.
