Die rätselhafte Verfärbung eines wertvollen Van-Gogh-Gemäldes lässt sich dank einer detektivischen Röntgenanalyse jetzt erstmals erklären: Ein vermeintlich schützender Firnis, der nach dem Tod des Meisters auf das Bild "Blumen in blauer Vase" aufgetragen wurde, hat demnach die Verfärbung einiger Blumen von einem leuchtenden Gelb zu einem matten Orange-Grau eingeleitet. Verantwortlich ist ein zuvor unbekannter Zersetzungsprozess, den Untersuchungen an der DESY-Röntgenquelle PETRA III und an der Europäischen Synchrotronquelle ESRF im französischen Grenoble erstmals enthüllt haben, und der sich an der Grenze zwischen Farbe und Firnis abspielt.
