Ian,

Maybe it is a dye and nothing to do with that I previously used it for color development. Anyways, this one time the color was dark red with b/w film and now it just comes out a bit reddish color when I do Adox film in Amaloco AM-74.

So it is quite common that the developer fluid comes out colored after developing? Maybe it is just normal. Sorry, but only just started developing.
