my limo seemed to change color when salting as well, ranging from clear to yellow (clear when i add vinegar, yellow when i add water).
my limo was pretty saturated with jim-jam before i salted it (had a orangey-reddish yellow), so i thought that might have been partially responsible.
maybe there are impurities in the limo that react??
also, you did use lime(CaOH), correct?
My wind instrument is the bong
CHANGA IN THE BONGA!
