💁🏻♀️ TIL: 🦋✨ #Butterfly wing #color comes from #pterin crystals that bend and scatter #light rather than absorb it, keeping colors vivid without fading.

I just finished a final mulling of 'raven black', a pigment made from carbonized common raven bones found on the dunes. (Not including the skull — that was left in place.)
Next to try it out as an ink.
