Try Rodinal with either APX 25 (don't know if it works with other Agfa films) or Foma 100. A lovely shade of green with dump out of the tank.
I think it depends on your developer and what kind of developer it is.
I've noticed that Diafine A tends to take on the color of the dye used heavily without a prewash. I'll presoak my 120 Arista films just so my Diafine isn't bright green. And other developers just come out looking like they went in even without a presoak. Maybe it's something to do with the developer canceling the color of the dye in some developers formulas perhaps?
My experience is the blue is neutralised in developer but not water. Sometimes it dissolves in the fixer and turns it blue, just depends on the film and developer I use.
In fact Ilford states not to do it with their films.
In fact, Ilford states that a pre-soak is not recommended with their films.
And quite recently, Simon Galley clarified further, that by "not recommended" Harman means, "not necessary", rather than "recommended against".
Pre-soaking works fine - just be sure to be consistent with whether or not you do it.
Some dyes are de-colorized by reducing agents such as the sodium sulfite in developers.
So have you every wondered why the prewash is always blue/cyan, but when you use no prewash the first developer is clear..
Ok so the developer is ID 11 were there is no prewash.

Believe it or not, two days ago I processed a 120 film without pre-wash for the first time ever and wondered exactly the same thing. I usually use a few washes until the water doesn't come out blue but decided not to bother just to see if there was any difference in development (there wasn't).
I was using D76, so basically the same.
I was thinking about starting a thread here, asking the same question!

this is something that has perplexed me for over twenty years, maybe a stupid question but can anyone enlighten me to what is happening here.
I believe that PE has stated a few times that these are sensitizing dyes. Remember, that AgBr by itself is only sensitive to UV light, and even AgI would only "see" blue or UV light. It's these special dyes that make an emulsion responsive to the parts of the light spectrum we want. After exposure these dyes are no longer needed.Each film (or manufacturer) has its own dye type embedded it in. I used to like to think that this universal dye insertion was a way to tell you what films you are actually running in case you had no packaging. red, blue, green, black etc'...
It would be interesting whether it is the alkaline property (as suggested by photo buddy) or the Sulfite ion (as suggested by Gerald Koch) which does the work. Next time I'll save some of that wash water and treat it with Sodium Carbonate and a pH 6 mix of Sodium Sulfite and Sodium Metabisulfite. I shall report here if nobody does that test first.As noted above the dyes get de-colorized/dissolved in the developer as part of its working process.
If you take your pre wash water which is colored, and drop just a few drops of developer in in there, you will see all the color vanishing before your eyes.
I used to do that demo at the first day of classes, it really is magic...
