These were both taken post-boil and post-chilling.

1.  Malts - no problem here and measurements are spot on.  I don't own any roasted malts at the moment.  Mill completely clean.
2.  PH - PH measurements are accurate. 
3.  Aeration - No difference in process
4.  Filtering/fining - yes grain beds well settled.  I do a constant recirc mash with HERMS.  Irish moss in both.
5.  No protein rest.  Only sacc rest at 150F
6.  I don't think this occurred but it's the only thing that I can think may have affected this unless my LHBS gave me golden oats.

I think I am going to chalk this up to "hmmm, weird".  If it tastes good I'm not going to worry any more about it.

2.6% flaked barley
3.2% C15
3.0% carapils

VERSUS

7.2% flaked oats
2.2% C15
1.3% carapils

Recipe 1
6.2% Crystal
Recipe 2
3.5% crystal

If that is Crystal 15?

I would assume the carapils/c15 % differences show a bigger color difference than the flaked oats vs barley.  FWIW you have beer... so its a good day right?
