Homebrew: Extract IPA is too dark

6.6 lbs Light LME
1 lb Golden DME

I added extra hops to the boil and dry hopped as well. It tasted good 5 days after bottling but had an odd creamy aroma.

LME will darken over time. Depending on where you got it from, it may have been old. Also, (not sure how long you've been brewing, so you may already know this) You should always take your pot off the fire when adding extract as it will drop straight down (almost) and can get scorched. Even after you mix it in well, you want the fire just hot enough to produce a slow rolling boil. A rapid boil is going to darken the wort.

There are lots of sources that will recommend only using light extract. I have gotten to the point where I stick with extra light or light only, unless the beer I'm brewing is supposed to be a stout/porter color.

An IPA doesn't need a lot of color anyway. In fact, Just about the lightest extract will give you enough color for an IPA.

You want a real challenge as an extract brewer? Try brewing a pilsner or a blonde ale that qualifies by color using only extract.

Well depending on the color you were going for that crystal 40 and victory will darken the beer up a good bit. Not black by any means but definitely not like a light in color ipa. That would probably give you a more amber color than a golden color.
