That's just the anti-halation dye on the back of the film dissolving, as it's designed to do.
It will discolor the first liquid used, whether it be pre-soak or developer.
This is absolutely normal. It happens with all films (except x-ray film), and is of no consequence whatsoever.
It's chemically inert and will not affect any photographic chemistry. The color will vary with the particular film in use, but it's irrelevant.

I too like the Yankee tank. The overall design of the tank is well thought out and it's very easy to use.
I have experienced some uneven development, but I attribute that entirely to operator malfunction. :D

I know about anti-halation layers, in fact I've wondered if I could improvise one on the X-ray film I've been using. I'm talking about some blue goop that turns my developer deep sky blue, and really does take 20 minutes to wash off. It's not conventional film. I'm not entirely sure what it is, possibly a color-separation film from the motion picture industry. It quite possibly is an anti-halation layer, but an extremely dense one designed for use in unconventional exposure situations.

Ilford hp4, the "scans" are quite crapy, its just a picture of a negative on a softbox app on my ipad... but thanks :)

And freaks me out every time i try some new sheet film :))
But i do agree - they are ok as intermediate solution. I have one as well as HP tank and both are kinda drying stations now, but i used them till i got Jobo b/c tray development isn't for me, apparently.

IMHO, if you want uneven negatives, and waste a lot of chemistry in the process, then go for it. There are cheaper, better options. I picked up an 8x10 unidrum and roller for $2 at the local camera shop. It is infinitely better than the Yankee.
Yes, the yankee is indeed crapola. Fill it with cement and use it as a canoe anchor. I use a Nikor 4x5 tank.

My example from the HP-Combi Tank. I think I overexposed a little, but it worked fine.
