I'd say just relax and give it some more time. The color is always going to look darker or off when its sitting in the primary because you are looking at 5+ gallons of a liquid versus 16oz in a glass. Its just how it works. I am sure there is a more scientific explanation to it, but its no different than say looking at a 2 liter bottle of dark soda and then pouring it in a glass. In the bottle, it looks black, in the glass, its brown.
I wouldn't worry about the flavor either. You just need to give it more time. Let the beer finish fermenting and clearing up. You still have a long way to go between letting it complete fermenting where it is now, conditioning in the bottle at room temp for a few weeks, and then cold conditioning in the fridge.
I am sure you made an excellent beer, it just needs time to finish the process.
