Weasil:
I have experienced blueish (or dark green) ketone before and have got to the end with fine results. As spric says, I think the weird color is a product of not distilling the safrole well enough. I know I told you this before, bro, but for me it was the sassafras. bad sassafras. And, from what I have been told, so was noj's. He got a little sample of REAL sassafras from a source who knew it was REAL from his own attempts and all of a sudden, his reaction worked. So, ask him. If you have the tone dude, even with semi-bad benzo, you should at least get some product. I have used dirt brown benzo and still got great results.
Also, in my experience, when the toulene is dis-colored and not foggy white...your fucked. Its bad tone, or not tone at all. I have experienced this many times. Your toulene should be foggy white even during the washes, up until you dry it with mag sulfate. After you filter the mag sulfate, toulene should be clear as day. (i don't know why, but it is, at least, in my experiences)
Of course, I am not sure if you have the same problem as I initially did (bad sassafras), but I'll tell you that it was the last fuckin thing I changed (success finally!), which really pissed me off because by that point I had wasted mega $$ and tons of chems. I thought it was this and that...and it was the sassafras. The al/hg is very forgiving so when you talk about bad benzo and pdcl2 or bad NaOH...I think you just trying to fix the wrong problems. Just for the fuck of it man, I would try a different batch of sassafras. But its up to you, of course.
Good Luck.
If some of us were not so far ahead, the rest of you would not be so far behind!
