Do you have to use a brown icing color to get brown fondant.. or can you use cocoa powder?

I know you can make chocolate fondant...but I am not sure how you would do it with the cocoa powder, how much you would need, etc.
The Wilton website says to add 4 ounces of melted unsweetened chocolate to a package of their fondant.

I just want to try and make a couple teddy bears for a baby shower cake

Satin Ice makes a chocolate fondant. You can also make candy clay to make roses, etc.

If you are looking for a small amount...

I made these dogs this past weekend using MMF with Americolor Cholocalte Brown and touch of Lemon Yellow.

I buy ready made chocolate fondant.

Don't know about you but the ready made chocolate tastes awful, to me anyway.

You can make chocolate fondant buy adding 1 oz melted semi-sweet chocolate and 1 T of cocoa (dutch produces a more pronounced flavor.) It will color a normal batch of fondant just a bit, so you want to add brown gel color to get a deep chocolate color.

I found this past week that it takes a LOT of Wilton to color it brown. Someone else posted that the Americolor gels are best to use.
