There shouldn't be anything that would keep you from drinking it. In fact, I think you really SHOULD drink it to see if it's suitable for further use.
If you taste anything "wrong", you can make a decision on what to do next. And remember, even if you think it's not all that great, you are removing almost all of the flavor at any rate.
As a final note, I am disregarding the intended purpose for this thread. We have a ZERO tolerance for discussing distilling here. So long as you recognize that and keep to discussing the yeast or anything PRE-distillation there won't be a problem. If you wish to discuss distilling, I highly recommend homedistiller.org.
Are you planning on freeze concentrating this wash? Surely, you aren't perpetuating a conversation about that which you were already told by a moderator cannot be discussed. I've never had yeast turn pink. I've also not used the turbo yeast before, so perhaps it is normal for that strain, not sure.
