I'm no scientist, but simple observation and playing around have produced 
pink CS.  When our CS is made with pure distilled water, it is a very clear 
light yellow color.  When we tried a couple of batches of CS with tap water, 
to see what the differences would be, the CS would turn a very bright pink 
and get somewhat cloudy.  When we made batches of CS with primarily distilled 
water, just adding a very small amount of tap water, the CS would turn pink 
(not always immediately either - but sometimes after sitting a day or two).  
We know our tap water has chlorine and fluoride in it.  We just figured it 
was the chlorine, as adding a drop or two of chlorine to the distilled water, 
would consistently turn the CS pinkish within several days.  We took 4 pint 
jars, using different "water" and then let it sit for a week to see what 
happened with the distilled, tap water, distilled with a drop or two of 
chlorine, and one with a mix of distilled and tap water. suzy
