This is exactly the decision I made this past April!! Originally I fell for Paraty in black but once I was close to purchasing I saw rock and loved the uniqueness of the color. After reading many TPF reviews about color change, fading, etc I decided to go with black. Although I still drool over rock, I'm thrilled with my choice and admire her daily. Chloe sure does make choosing a color difficult with all the gorgeous choices. My final decision was made when I saw pictures of fading on someone's rock - I didn't want to be bummed out about that in a couple of years. I like my bags to stay in great shape and take care of them despite regular use. I didn't want to chance it considering how pricey these bags are. So much to think about! I think you'll love your black Paraty.
