I've really been holding back on saying anything but this is ridiculous at this point.
I really have to say something because I deal with Leather and DVD Headrests for a living.

That is not a lighting trick or effect otherwise your OEM headrest would not look Gray, it would look beige. If you want to disagree that is your decision but at this point and looking at all the pics in this thread it is so obvious it sickens me... I'm going to call BS. Seriously!
These are 2 different colors. I have seen these headrests and they look nothing like the OEM color and I'm only saying that because it's true. Look at the pics it's soooo obvious.
Your seat and that headrest are obviously two separate colors. Whats the real story morning glory?
