I have noticed some cars (J35 Hondas specially) turn the oil dark quickly while the Toyota's I have owned stay much cleaner and lighter in color. These are in new vehicles that have always used synthetics and changed and 6k to 7k.
I used to be worried about it but have always put over 200K on these vehicles with no issues. Current J35 I have have 214k and 90K with no issues but oil comes out super dark.
