Quite surprised acetone didn't take the dye off.Does solubility vary by colour?
Seems to me you're not properly controlling for color. Are the visual differences due to different dye solubilities?
You would need a modified pulse sequence (a very long acquisition time, 45 degree angle) to see proton signals from macromolecules in your NMR so the fact you don't see a polymeric stuff in your jelly beans does not mean there isn't any
This is all riveting stuff. I hope you continue to tackle some more of life's unanswered questions in the future, such as why the Baran group see fit to wear their soiled labcoats in the Scripps cafe while I'm having my lunch.

DMSO doesn't have residual peak?
