I have an unused bottle (90 mL) of Noodler's Polar Black that I got with some pens I bought. The problem is, I already have a few bottles of black, and don't really need another. Some colors/brands that I'm interested in are:

Waterman Florida Blue
Noodler's Habanero
Noodler's Antietam
Anything you are looking to get rid of

I'm pretty new to fountain pens, and lately have been trying to acquire some more non-standard ink colors, since that's one of the benefits of using a fountain pen. I'm currently using Noodler's Cayenne, MB Racing Green and PR Black Magic Blue. So if you have any other colors that you are looking to get rid of in exchange for Polar Black, then I'm your guy.
