Chicago-L.org has a handful of renderings.
I'm happy to see the blue walls are gone. They looked terrible. The off-white reminds me of my favorite trains - the 2200 series. Of course, they started off with a greyish interior and padded black seats but ended up with the off-white walls. I was four when they debuted and five when the Kennedy extension was opened. Still remember riding from Jefferson Park to Desplaines, back downtown, out to Cicero-Berwyn, and back to Jefferson Park. We rode the 2200's, 2000's, ad 6000's that day. Although I was in college when the Rosemont and O'Hare extensions opened, my dad and I repeated our excursion. On all three trips we sat at the front of the train. I did not, however, sit on his lap the last two times.
Thanks for indulging me in this little diversion from the topic. I'll have to repeat that trip when the 7000's arrive.
