There is only one other person that I can think of off hand that has had a problem with colored fluid going clear, that would be SparkyJJO. IIRC, he only used masterkleer and dyes (every green dye he could get his hands on IIRC), some of them faded away to clear after a short while. As you can see, it's a completely different scenario than with SNiiPE. Everyone else I can think of, the color or UV effect only faded but the fluid did not go clear.
