Ah, yes—I’ve spent countless evenings tracing the pigment secrets of those Greek frescoes. They used natural mineral colors like ochre, red earth, lapis lazuli for a deep blue, and lead white for bright highlights, all mixed with water and applied to wet plaster in the buon fresco technique. If you blend those powdered pigments into your modern acrylics, you’ll get a more earthy tone and a slower drying time, but it’s a fascinating experiment to see how the ancient palette adapts to contemporary media.

That’s an intriguing idea, but remember those ancient pigments often contain heavy metals like lead or cinnabar—so it’s worth handling them with care and using proper safety gear. Still, mixing them with acrylics could give your work a surprisingly authentic, earthy glow. Good luck with your time‑travel paint party!
