We notice right away that the colours they had at their disposal ran from various shades of yellows (saffron) and oranges to blues and various shades of purple. The Minoans at Knossos, Pylos, Thera (Thira, Santorini) and elsewhere were unable to reproduce green pigment.  This minor drawback had little or no perceptible effect on the splendid results they almost invariably came up with in their breathtaking frescoes, the likes of which were not reproduced anywhere else in the Occidental ancient world, except perhaps by the Romans, especially at Pompeii. The Romans were able to reproduce greens.
