[IBU] two styles in one batch of beer

[Adam Draeger]

After years of 5gal all-grain, I brewed my first 10 gallon batch of beer and
am completely baffled at my results.  see photo attached.

I was targeting a German Alt and thought I had chocolate malt (which I
didn't) so I tried to roast some myself that morning and was only able to
achieve 100L or so.  (not the 400L)  anyways so I figured it would be a
Blonde Alt or a Dunkel Kolsch.  after brewing I chilled with an immersion, I
put 3.5 gal into one plastic primary and the rest (4.5 gal) into the other
primary.  The 2nd primary had my hop sludge, so I expected the only
difference it to contain more hop aroma.  I also wanted to parallel liquid
(WLP029) and dry yeasts (nottinghams), so I pitched those respectively.
once I saw them in the secondary I was perplexed as one was blonde and the
other was dark.

Did maybe my hop sludge absorb the dark colors during the boil and re-submit
them into the fermenter?
that's my only theory so far.
Anybody want to throw their two ounces in?
