Well, according to the latest specs, it looks like there will be eight color options and from what I can see, Infiniti doesn't seem to change up their color options a whole lot from car to car, so I'm going to assume that the color choices are also going to be very much the same as before.
So it looks like the only colors we haven't seen that make up the remaining three are Malbec Black, Moonlight White, and Black Obsidian...
I have the Malbec Black right now and everyone loves it. I'm hoping not only do they bring back the Malbec Black in the Q50, but also bring back the red leather seats as in the Limited Edition G from 2011 and the current IPL coupe/convertible.
