Hi, With the bulk Chems I buy, bearing in mind I dissolve the Phenidone in a touch of alcohol as it does not do well going into solution with water. Wouldn't imagine that would change color. Sepia color I am tlaking about happens when the clear A solution is added to the clear B solution the color quickly shifts to a fain sepia color. That actually is a positive indicator that the two chems are in fact preforming properly.
