I pre-soak the film and some times I get some color when pouring the developer. Can not remember, but one film does make the developer very dark brown color, like coffe.
And my last bottle of rodinal that I bought come with Adonal name, I took an old agfa rodinal label from a old bottle and glue it over the adonal. Presto, Agfa Rodinal to use with apx 100 and others!
