It's probably a lot lighter than you think. It's hard to judge inside the carboy. Take a sample with a wine thief or turkey baster and put it in a glass.
Note that when there is a lot of yeast floating around, it will look light. Once the yeast falls out of suspension, it will look very dark (because the reflective yeast aren't there). But when you get it out of the carboy and into a glass, it's back to light again.
