Some of the Blake's have a blue suede lining (the Putty I looked at today does). I have been a little paranoid about getting the lining of my Sophia dirty, but I'm trying to be careful with it, and I figure that no one will see it but me anyway...
After my first Burberry tote got pen marks on the suede lining the first week I had it, I learned to put pens, makeup and anything else that could make marks into waterproof cosmetics cases before stowing in my bags. That's helped a lot.
