When you change your oil, there are still pockets of residual oil in the engine. The residual mixes with the new stuff, and makes it darker. The longer you go between changes, the darker it will be post-change. Some engines store more residual than others. Auxillary oil coolers and anti-drainback valves in particular can make for additional residual capacity.
Since this is your first change, you may want to change the oil a second time just to be sure you get off to a fresh start.
