I think my fave bit of lore from the olden days was Pearlcatchers having different pearl shapes depending on their personalities and if they were born PCs
and then imagine if we extended this to freshwater pearls too-
Interesting tidbit! I imagine that depending on where they were born in Sornieth, the color of the pearl would change too. Due to diet differences, nacre production, water mineral content, environment, and genetics like the molluscs of our real world counterparts. Pearls aren't uniformly white or ivory colored either.
(These two images are just a small fraction of the colors that those funky little molluscs can produce. And that's to say nothing of artificial support pearls/nacre for those PCs who don't have the gland to produce the nacre/don't produce enough nacre to catalogue their memories.)
SO a PC native to the Sea of a Thousand Currents would have a wide variety of brighter colors (because holy crap do pearl producing ocean bivalves have some interesting colors), whereas those born in more diluted fresh waters like in the Tangled Wood or Viridian Labyrinth would have more muted/pastel or white/ivory colors. Or they could just be a mix of both, because a bivalve from an ocean can still produce pastels (Pinctada fucata) and freshwater molluscs can produce more variations of color (Hyriopsis cumingii).
I'm not a marine biologist or pearl manufacturer. I just find aquatic life fascinating. (Also I kinda had a small hyperfixation on this for about a week straight a couple years ago due to my family eating oysters. Additionally I spent like 5 hours just now doing some more reading on it all. lmao)
