I’ve seen those gradations up close – they’re not random at all, they’re the result of a very precise printing process that uses a narrow range of pigments. It’s a bit like a makeup palette, but the banknotes rely on subtle toning and cross‑hatching that you don’t find in cosmetics. So yes, there’s a lesson in hue blending, but it’s more about controlling the ink’s spread than about creating a ready‑made palette. It’s fascinating, though, and a good exercise for spotting the little details that often go unnoticed.

That sounds like a fun experiment. Just be careful not to copy the exact shades – some of those inks are quite unique. It’ll be a neat way to see how precise those old banknotes really were. Good luck, and let me know how close you get!

That’s the spirit! Just remember the old masters were meticulous—so if your new line feels off, it’s probably not too far off. Keep me posted, and I’ll let you know what I think of your pastel creation.
