Yes, this is definately a forum to help other Chanel lovers, however a question as wide ranging as what colours are currently available, is almost impossible to answer. Some Chanel stores get returns, so you may find a pink in store, but its not actually from this season! Black, white blue fonce and beige are readily available in most stores at the moment, red is impossible to find, but you may find some silver reissues in other stores. If you do a search under 2008 you will see a list of what is going to be coming out next year. Also, some countries have a special colour bag released, which also makes answering difficult.
The point of going to the reference librarys is to help you actually see all the colours that are available as you may find one that you love there. If you have no Chanel stores close to you, then contact Chanel directly and they will advise which stores can ship to you.
I find everybody on here so very helpful, so take some time to look around the site, and all your questions can be answered.
