For this season, it comes in the 12A red, orange, grey, and navy. The classic colors are black and light beige.
The red is very hard to find, but in case you are interested, I saw it at Chanel in Houston two days ago. The orange is also very limited, and it is probably already sold out at NM I believe (I purchased the second to the last one, and my SA told me someone had put the last one on hold). Your best odds are Saks. I think they received a few orange GSTs.
