What colors should I mix to make a deep dark teal colored fondant?

Wilton and Americolor make teal gel colors that you can use. It just requires a lot of it to get it dark.

Would a hint of black do it?  or navy?    just curious because I have the same problem and dont want to mess up a whole mixer full.

What she said...only I think Americolor gives a darker teal color. And no I wouldn't use black to darken. Keep in mind that colors will deepen if you let them set for a while. Mix in your color then wrap the fondant up in plastic wrap for an hour or so.

AWilton has teal, u just need to add a lot to the sugarpaste to make it dark
