First homebrew....a question.

I think you probably meant the target is 1.016. It may be done at 1.020. Wait 2-3 days and measure again to be sure.

 

^what Vikeman said. I will add that the flavor is almost certainly going to change between now and being finished/carbonated, so don't put too much stock in what it is now, wait till finished and decide.

 

Most beer will undergo drastic flavor changes in carbonation. Also, you may have yeast in suspension that causes the color to appear lighter than it actually is.
Having an FG .004 off really isn't too bad in the scheme of things, there are things that can cause that difference, including temp changes, stratification of the beer, if your volume is off a bit, and even some bubbles in the testing tube.
Recipe and procedure might also help to see if there is a problem.
Personally, I would let it ride another few days minimum (I personally let things sit in primary for at least 3 weeks to be sure it's done) and then if you're sure it's done, bottle and condition. The final end product may surprise you.

 

Actual color won't really change, though yeast and other particles may settle out. Is there something particularly bothering you about the taste?

 

Closer to a quad in what way?

 

Two things:

1. Was the recipe modeled after a certain beer that gave you the expectations that you were looking to mimic? It's hard to match exactly to a known flavor of a specific brew with a clone recipe, so your expectations may have been over zealous. Were you possibly expecting a bit of a roasted malt flavor in this beer?
2. Looking at your recipe, with a pound of black malt, your beer should have been pretty dark. Was the grain whole or cracked?

 

if it seems to taste closer to a quad then you're probably tasting the yeast. as others mentioned give a few more days(or longer). if you're able to do a cold crash, a good bit of the yeast will fall out and you most likely won't taste a lot of yeast like you are probably tasting now.

 

As your first homebrew ... what were you hoping for after fermenting the wort for two weeks?

 

Make sure it is finished fermenting, bottle it, wait two weeks for it to carb, then give one a try. It likely won't be great, but you will have a much better idea of what you have on your hands at that point. RDWH(Someone Else's)HB.
