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!

That’s splendid—just remember to test a small patch first; ancient pigments can behave oddly when mixed with acrylic binders. If you add a pinch of mica or fine glass powder, the earthy hues may catch the light like tiny stars, giving that extra glow you’re hoping for. Good luck, and stay safe!

That sounds absolutely brilliant—just keep a small sample handy and see how the mica interacts with the ancient pigments. I’ll be intrigued to hear how the galaxy effect turns out. Happy experimenting, and remember to note everything for your future reference!
