I'm comparing clean crystal freeze precip (very slightly off white) DMT to the same batch but redissolved in acetone. After one week the redissolved stuff has changed color noticeably while the white crystal form DMT keeps it's white off white color.
Well, then that's not a valid comparison since you cannot compare dmt colour in crystal vs dmt colour in solution.
But please, I think I might be misunderstanding your post, since the way it is worded makes it open to more than one interpretations. What I read is that you dissolved freeze-precipitated white-orange spice in acetone and it changed colour. Again, did you evaporate it to make colour comparison? And why, out of curiosity you'd leave it in acetone for 1 week? Or your redissolved stuff was changing colour while acetone was evaporating. Please try to be more elaborate and punctual with the information you post. Again, if I got you right (as per my first sentence) then your comparison is invalid and your conclusion flawed.
